1. Diamond Carat
The Weight Behind the Brilliance
Every diamond is a miracle of time, pressure, and nature — crafted deep within the Earth and brought to light by human artistry.
Its sparkle and fire are what captivate the heart, but its carat weight is what determines much of its rarity and value.
At Zorba Diamond, we believe that understanding a diamond’s carat is the first step toward buying it wisely — not just emotionally.
What Is Diamond Carat?
Simply put, carat refers to the weight of a diamond — not its size.
One carat equals 0.2 grams, roughly the weight of a raindrop.
To ensure precision, jewellers use the point system, where:
- 1 carat = 100 points
- 50 carat = 50 points (often called “half a carat”)
Even a small variation in carat weight — as little as 0.01 carat — can significantly impact a diamond’s price. That’s why carat measurement is one of the 4Cs of Diamond Grading:
Cut, Colour, Clarity, and Carat Weight.
Carat Weight vs. Total Carat Weight (TCW)
When you hear the term “total carat weight”, it refers to the combined weight of all diamonds in a jewellery piece — not just a single stone.
For example:
If your earrings have two diamonds totalling 1 carat, it means each stone is approximately 0.50 carat.
This distinction is essential when comparing diamond jewellery — especially when you’re looking at rings, pendants, or bracelets that feature multiple stones.
⚖️ Carat vs. Karat — Know the Difference
A common confusion among jewellery buyers is between carat (ct) and karat (kt):
- Carat (ct) measures the weight of gemstones like diamonds.
- Karat (kt) measures the purity of gold, with 24K representing pure gold.
💬 Zorba Tip: Next time you’re admiring a gold diamond ring, remember — one “weighs the stone,” the other “defines the metal.”
🌍 A Bit of History — From Carob Seeds to Carats
The word carat originates from the carob seed, once used by ancient traders as a natural weight standard due to its uniform size.
In 1907, the metric carat (200 milligrams) was adopted as the global unit of measure.
Today, this standard ensures universal precision and consistency in diamond trading across the world.
How Carat Weight Affects Price
Carat weight plays a major role in determining a diamond’s price and rarity.
Larger diamonds are much rarer than smaller ones — hence, their value rises exponentially, not linearly.
However, it’s important to remember:
A diamond’s true worth depends on all four Cs, not just its weight.
Two diamonds of equal carat weight can have very different prices depending on their cut quality, colour grade, and clarity level.
Carat Weight and Size — Not Always the Same
Many buyers assume that heavier means larger — but carat weight doesn’t always equal size.
Two diamonds with the same carat weight can appear different in size depending on their cut and proportions.
For example:
- A deeply cut round diamond may appear smaller from the top than a shallow-cut oval diamond of the same weight.
- The cut style determines how light is reflected — affecting both size perception and sparkle.
💬 Zorba Tip: Always balance carat and cut — a perfectly cut diamond of slightly lower weight can outshine a heavier one with poor symmetry.
💎 Shape and Carat — How They Influence Value
Different shapes yield different visual sizes for the same carat weight:
- Round Brilliant – Most popular and sparkly, often pricier.
- Oval / Marquise – Appear larger due to elongated shapes.
- Emerald / Asscher – Elegant but reflect less fire, appearing smaller.
That’s why two diamonds of identical carat weight may look different in size — and differ in price.
✨ Magic Sizes — The Carat Milestones
In the diamond world, certain weights like 0.50 ct, 1.00 ct, and 2.00 ct are known as “magic sizes.”
A 0.99 carat diamond may look nearly identical to a 1.00 carat diamond — but can be priced significantly lower.
💬 Zorba Tip: “Buy shy.” Choose just below a magic size (e.g., 0.90 ct or 1.90 ct) to get the same look at better value.
Does Bigger Mean Better?
Not always.
A larger carat diamond may not necessarily be more beautiful.
If the cut is poor, it will lack brilliance, appearing dull despite its size.
A smaller diamond with an excellent cut can often outshine a heavier one.
💬 Zorba Insight: True beauty in a diamond is not in its weight — but in its light.
💍 Smart Buying Tips from Zorba Diamond
- Balance carat and cut. A well-cut diamond will always appear brighter and more lively.
- Know your priorities. If sparkle is your goal, focus on cut; if size matters, find your sweet spot in carat.
- Buy just below magic sizes. Save smartly without losing visible size.
- Consider the setting. A halo or cluster design can make smaller diamonds look larger.
- Always buy certified. Ensure every diamond comes with an authenticity report from GIA, IGI, SGL, or GSI.

2. Diamond Clarity
The Purity of Perfection
A diamond’s beauty is timeless — its sparkle, brilliance, and grace unmatched.
But behind every luminous gem lies a story written by nature itself — of pressure, heat, and patience spanning millions of years.
Every diamond is unique, born with tiny natural features that distinguish it from all others. These delicate “birthmarks” — known as inclusions and blemishes — are what gemologists study when grading a diamond’s clarity.
At Zorba Diamond, we believe that clarity is not just a measure of perfection — it’s a reflection of authenticity.
💠 What Is Diamond Clarity?
Clarity refers to how pure and clean a diamond appears — both inside and on its surface.
It measures the presence (or absence) of inclusions (internal marks) and blemishes (surface marks).
Because natural diamonds form deep beneath the Earth’s crust under extreme conditions, most carry tiny imperfections.
These are not flaws — they are nature’s fingerprints, making each gem one-of-a-kind.
The fewer and less visible these inclusions are, the higher the diamond’s clarity grade, and often, its value.
💎 How Clarity Affects Value
Clarity and value are closely related:
- Fewer inclusions = higher clarity = higher price.
- More inclusions = lower clarity = lower price.
However, not all inclusions are visible to the naked eye — many are microscopic and do not affect beauty or brilliance at all.
What truly matters is how the inclusions impact the diamond’s transparency, sparkle, and symmetry.
💬 Zorba Insight: Two diamonds can look identical to your eye — yet differ greatly in price simply because of microscopic clarity differences.
🔬 The Science Behind Diamond Clarity Grading
Each diamond is carefully examined by expert gemologists under 10x magnification, using a loupe or microscope, and viewed from the face-up position.
A diamond’s internal pattern of inclusions is recorded on a clarity plot, much like a fingerprint.
This plot helps identify the diamond and ensures its traceability in certification.
These evaluations result in a clarity grade that follows a global standard used by labs like GIA, IGI, and SGL.
💎 The Diamond Clarity Scale
GradeMeaningDescriptionFL / IF (Flawless / Internally Flawless)PerfectNo inclusions visible even under 10x magnification. Extremely rare and expensive.VVS1 / VVS2 (Very Very Slightly Included)Near PerfectInclusions are extremely tiny and difficult to see even under magnification.VS1 / VS2 (Very Slightly Included)ExcellentMinor inclusions barely visible under magnification.

Lower transparency and brilliance.
💬 Zorba Tip: Many VS and SI1 diamonds look flawless to the naked eye — offering exceptional beauty at better value.
💎 How Inclusions Are Judged
Clarity is influenced by five key factors:
- Size of the inclusion
- Number of inclusions
- Colour or contrast of the inclusion
- Position (centre vs edge)
- Nature (type and visibility)
Inclusions closer to the centre of the table (top view) are more noticeable and affect sparkle more than those near the edges.
💍 Choosing the Right Clarity Grade
When selecting your diamond, ask yourself:
- Do you want absolute perfection, or visible brilliance at a better value?
- Are you buying for aesthetic beauty, investment, or daily wear?
Here’s how to decide:
- FL – IF: For collectors and investors seeking perfection. Rare and exquisite.
- VVS: Perfect for engagement rings — stunning purity, nearly flawless to the eye.
- VS: Excellent choice for fine jewellery — great balance of quality and price.
- SI: Smart buyers’ favourite — beautiful, budget-friendly, and eye-clean.
- I: Ideal for fashion or statement pieces where size matters more than purity.
💬 Zorba Tip: A diamond doesn’t need to be flawless to look flawless. Choose what pleases your eyes, not just what’s written on paper.
💎 Common Buying Mistake to Avoid
Many first-time buyers assume higher clarity automatically means better investment — but clarity is just one of the 4Cs.
A VS1 or SI1 diamond with a perfect cut often looks more radiant than a flawless diamond with a poor cut.
💬 Zorba Insight: Prioritise cut first, then colour and clarity. The sparkle you see is the result of how light travels — not how flawless the diamond’s surface is.
💫 Smart Buying Tips from Zorba Diamond
- Look for “eye-clean” diamonds. They appear flawless without magnification but cost less than high-clarity stones.
- Balance clarity with cut and carat. Don’t overpay for invisible perfection.
- Always buy certified. Ensure clarity grades are verified by labs like GIA, IGI, or SGL.
- Ask to see under magnification. A transparent jeweller will always show you inclusions openly.
- Trust your instincts. The most beautiful diamond is the one that speaks to your heart.

3. Understanding Diamond Colour
The Beauty of No Colour
Diamonds are often called the fire of light — brilliant, pure, and endlessly captivating.
And yet, in the world of fine diamonds, the most desired colour is not a colour at all.
At Zorba Diamond, we believe true beauty lies in purity — and when it comes to diamonds, that means the absence of colour.
Here’s everything you need to know about this fascinating “C” — and how diamond colour defines brilliance, beauty, and value.
💠 What Does Diamond Colour Mean?
In everyday life, colour means vibrancy — red, blue, yellow.
But in the world of diamonds, colour means the absence of hue.
A truly colourless diamond allows light to pass through effortlessly, breaking into a spectacular rainbow of fire and brilliance.
The more colour a diamond has — often a faint yellow or brown tint — the less purely it reflects light, and the less brilliant it appears.
The purest diamonds are 100% carbon, untouched by impurities.
But such perfection is extraordinarily rare, which makes colourless diamonds among the most valuable treasures of the earth.
💎 How Colour Affects a Diamond’s Value
Diamond colour is one of the 4Cs — alongside Cut, Clarity, and Carat — that determines the worth of every stone.
When light enters a diamond, it bounces between its facets, creating the fire we see.
Even a faint trace of colour can interfere with this refraction, reducing brilliance and light return.
In simple terms:
- More colour → Less sparkle
- Less colour → More brilliance and higher value
That’s why, at Zorba Diamond, we carefully grade and source diamonds with the optimal balance of purity and light performance.
📊 The Diamond Colour Scale (D–Z)
The international diamond colour grading system — developed by the Gemological Institute of America (GIA) — ranges from D (colourless) to Z (light yellow or brown).
Here’s how to understand the spectrum:
Colourless (D, E, F)
- The most pristine and rare diamonds.
- Absolutely colourless to the naked eye — D being the highest grade possible.
- Best set in platinum or white gold, which complements their icy brilliance.
💬 Zorba Tip: These diamonds represent the ultimate in elegance and purity.
Nearly Colourless (G, H, I, J)
- Appear colourless to most eyes; only experts detect faint warmth under magnification.
- Offer excellent value without visible compromise.
- Ideal for both white and yellow gold
💬 Zorba Tip: A perfectly cut H-grade diamond can look as radiant as a D — at a much smarter price.
Faint Colour (K, L, M)
- Subtle yellow or warm undertones visible under bright light.
- Popular among buyers who prefer a soft, vintage tone.
- Best paired with yellow or rose gold to complement the tint.
💬 Zorba Tip: A K-grade diamond in a yellow gold setting can appear beautifully balanced.
Very Light (N–R) & Light Colour (S–Z)
- Noticeable yellow or brown tint, even to the naked eye.
- Rarely used in fine diamond jewellery due to limited sparkle.
- Often reserved for decorative or fashion pieces.
🌈 Fancy Coloured Diamonds — The Exception
While the colourless diamond reigns supreme, fancy coloured diamonds (blue, pink, green, red, and yellow) are a different universe altogether.
Their colour isn’t considered a flaw — it’s a feature of rarity and allure.
The more vivid and intense the hue, the higher their value.
Famous examples include:
💎 The Hope Diamond — deep ocean blue
💎 The Pink Star — vivid pink brilliance
💬 Zorba Insight: Colourless diamonds express timeless beauty; coloured diamonds express personality and art.
💍 How to Choose the Right Diamond Colour
When selecting your diamond, consider these expert tips from Zorba Diamond’s master gemologists:
- Match Colour with Metal:
D–F grades shine best in platinum or white gold.G–J grades blend well with both white and yellow gold.K–M grades glow beautifully in yellow or rose gold. - Prioritise Cut Over Colour:
A superior cut enhances sparkle and masks faint colour — ensuring your diamond shines brighter than its grade. - Stay Within the “Eye-Clean” Zone:
Choose diamonds that appear colourless to the naked eye, even if technically lower on the scale.
💬 A well-cut G or H diamond often looks identical to a D in real-world lighting. - Always Demand Certification:
Only purchase certified diamonds graded by GIA, IGI, SGL, or GSI.
These reports guarantee the colour grade is genuine and verified. - Let the Setting Work for You:
A smart metal choice can enhance your diamond’s colour perception — a secret every fine jeweller knows.
💎 Zorba Diamond Promise: True Light, True Colour

4. Diamond Cut
The Art of Brilliance
Every diamond tells a story — a story written in light.
And of all the factors that define a diamond’s beauty, its cut is the one that truly brings that story to life.
The cut is what transforms a rough crystal into a masterpiece of brilliance, fire, and sparkle. It’s not about shape — it’s about precision, proportion, and perfection.
At Zorba Diamond, we believe the cut is the heart of every diamond.
Because only a perfectly cut diamond can capture light the way love captures hearts.
💠 What Is Diamond Cut?
A diamond’s cut refers to how well its facets — the tiny surfaces that act like mirrors — are aligned, angled, and polished to reflect light.
It is the only one of the 4Cs shaped entirely by human craftsmanship.
Unlike shape (which defines the outline — round, oval, princess, etc.), the cut defines how brilliantly the diamond interacts with light.
A well-cut diamond reflects light back through its top, creating a captivating sparkle.
A poorly cut diamond, no matter its size or clarity, will appear dull and lifeless.
💬 Zorba Insight: The true magic of a diamond lies not in its size — but in how it plays with light.
💎 The Three Elements of Diamond Brilliance
A masterfully cut diamond exhibits three key properties that define its beauty:
1. Brilliance
The white light reflected from both the internal and external surfaces of the diamond. It’s what gives the diamond its bright, lively look.
2. Fire
The colourful flashes of light that dance within the diamond as it disperses light into the full spectrum — reds, blues, and yellows — a prism in miniature.
3. Sparkle (Scintillation)
The flashes of light that appear when a diamond or the observer moves. This dynamic shimmer is what gives a diamond its life.
💬 Zorba Tip: A perfect diamond balances all three — brilliance, fire, and sparkle — in exquisite harmony.
⚒️ How Cut Quality Impacts Beauty
The cut quality depends on proportions, symmetry, and polish.
Even a slight variation in facet angles can dramatically affect how light enters and exits the diamond.
Cut Grade
Description
Excellent
Ideal proportions; maximum brilliance and fire.
Very Good
Exceptional sparkle with minimal light loss.
Good
Decent brilliance; some light escapes.
Fair / Poor
Noticeable dullness; light leaks from sides or bottom.
💬 Zorba Tip: Always prioritise cut — even above carat. A smaller, well-cut diamond will outshine a larger, poorly cut one every time.
💎 Popular Cutting Styles
Different cutting styles enhance different visual effects:
1. Brilliant Cut
Facets are designed to maximise light reflection.
The Round Brilliant — with 57 or 58 facets — is the most iconic and radiant cut.
2. Step Cut
Facets are arranged in parallel lines, like steps.
This cut emphasises clarity and elegance rather than sparkle.
Emerald and Asscher cuts fall under this category.
3. Mixed Cut
Combines brilliance and step styles — offering sparkle and symmetry together.
Princess and Radiant cuts are perfect examples.
4. Fancy Cut
Any non-round cut — from heart to pear to marquise — is considered fancy.
These shapes bring individuality and character to your diamond.
💍 Popular Diamond Shapes and Their Allure
Each diamond shape has its own personality and charm.

💡 How to Choose the Perfect Cut
When selecting a diamond for your ring, pendant, or bracelet, consider these expert tips:
- Inspect Under Multiple Lights:
View the diamond under spot, diffused, and natural daylight to truly appreciate its sparkle. - Prioritise Cut Over Size:
A perfectly cut 0.9 ct diamond can outshine a poorly cut 1 ct diamond. - Look for Certification:
Always ensure your diamond’s cut grade is certified by reputed labs like GIA, IGI, SGL, or GSI. - Mind the Facets:
The more precise the facets, the more light performance. Round brilliant cuts have the ideal balance. - Balance Your Priorities:
If you value brilliance, go for excellent cut grades. If you prefer elegance and clarity, step cuts might suit your taste.

5. Diamond Cuts & Shapes
The Geometry of Brilliance
When you first see a diamond ring, your eyes are instantly drawn to the size and sparkle of the stone.
That shimmer isn’t just about its size — it’s about how it’s cut.
Among the 4Cs that define a diamond’s beauty — Cut, Colour, Clarity, and Carat — it’s the cut that brings the gem to life. A well-cut diamond captures light, releases fire, and radiates brilliance that no other gemstone can match.
At Zorba Diamond, we see the cut not just as craftsmanship, but as artistry in precision — where each facet is carved to perfection to make your diamond truly shine from within.
💠 Cut vs. Uncut Diamonds: From Earth to Elegance
A raw diamond, fresh from the earth, looks nothing like the luminous gems you see in fine jewelry.
These uncut diamonds are rough crystals — translucent, uneven, and sometimes tinged with brown or yellow hues.
While they hold a rustic beauty, they lack sparkle.
Only through expert cutting and polishing does a diamond awaken its full potential — transforming from a raw stone into a masterpiece of fire and brilliance.
💬 Zorba Insight: Every cut unlocks a diamond’s personality — the art lies in knowing how much light to set free.
💎 The Secret Behind a Perfect Cut
Cutting a diamond is both science and poetry.
Each rough diamond can be shaped in multiple ways — one large gem or several smaller ones — depending on its natural structure.
The two main elements that determine how a diamond is cut are:
1. Proportions
The relationship between a diamond’s angles, depth, and table defines how light interacts within it.
- If it’s too shallow, light escapes through the bottom — the diamond looks dull.
- If it’s too deep, light leaks from the sides — the stone looks smaller and darker.
The perfect cut finds the sweet spot — where light enters, reflects, and exits through the crown in a brilliant flash.
Other proportion factors include:
- Table % (the flat top surface)
- Depth %
- Crown and Pavilion Angles
- Girdle Thickness
- Culet Size
💬 Zorba Tip: When comparing diamonds of the same carat, the one with lower depth % will appear larger — without costing more.
2. Shape
A diamond’s shape defines its outline — round, square, oval, heart, or marquise.
Each shape has a different way of reflecting light and influencing the stone’s perceived size and style.
While cut affects sparkle, shape defines personality.
💎 The Most Popular Diamond Cuts and Shapes
Every diamond shape tells a story. Some speak of classic elegance, others of bold individuality.
Here’s your guide to the ten most celebrated diamond cuts:
1. Round Brilliant
The world’s most iconic cut — featuring 57–58 facets designed for maximum brilliance.
Its perfect symmetry and light reflection make it the benchmark for sparkle and the top choice for engagement rings.
💬 Zorba Tip: A well-cut round diamond hides minor colour and clarity imperfections beautifully.
2. Princess Cut
Modern and bold, the princess cut combines the sparkle of a round diamond with a square silhouette.
Its pointed corners and clean lines exude sophistication — perfect for contemporary jewellery.
3. Oval Cut
A graceful variation of the round cut, the oval offers similar brilliance with a more elongated shape.
It gives the illusion of longer fingers and larger size — an elegant choice for rings.
4. Marquise Cut
Named after the Marquise de Pompadour, this cut features pointed ends and an elongated oval form.
Its unique shape maximises surface area, making the diamond appear larger than its carat weight.
💬 Zorba Insight: A marquise diamond symbolises grandeur and confidence — ideal for statement pieces.
5. Pear Cut
Also known as the teardrop shape, the pear combines the round and marquise cuts for a romantic, feminine look.
When worn as a pendant or ring, it flatters the hand with elegance and grace.
6. Emerald Cut
A symbol of timeless luxury — the emerald cut’s rectangular step facets create a “hall of mirrors” effect.
It highlights clarity and elegance rather than sparkle. Favoured by icons like Elizabeth Taylor and Beyoncé, it’s a mark of sophistication.
7. Cushion Cut
Also known as the pillow cut, it blends vintage charm with modern brilliance.
Rounded corners and large facets give it a soft, glowing radiance — perfect for those who love classic romance.
8. Radiant Cut
A modern hybrid of the emerald and round cuts.
It features the depth of the emerald and the sparkle of the round, creating a dazzling balance of structure and fire.
9. Asscher Cut
Similar to the emerald cut but square in shape, the Asscher exudes a vintage, Art Deco allure.
With stepped facets and clipped corners, it’s both bold and refined.
10. Heart Cut
The ultimate symbol of love and sentiment.
This shape requires precision and expertise — each curve must be perfectly balanced.
A heart-shaped diamond is rare, romantic, and deeply personal.
Bonus: Trillion Cut
A triangular cut that exudes modern glamour.
Used as either a centrepiece or side stone, the trillion cut delivers a sharp, contemporary sparkle.
💎 How Diamond Cuts Are Graded
Diamond cuts are graded on how efficiently they reflect light.
The five standard grades are:
Grade: Excellent
Description: Perfect proportions, maximum sparkle.
Grade: Very Good
Description: Brilliant and lively; nearly identical to Excellent in natural light.
Grade: Good
Description: Bright, but slightly less fire and reflection.
Grade: Fair
Description: Noticeable light loss, less brilliance.
Grade: Poor
Description: Dull appearance, little or no sparkle.
💬 Zorba Tip: A “Very Good” cut diamond often looks just as stunning as an “Excellent” one — at a better price.

6. Colourful Diamonds
The Spectrum of Rarity
“But I thought the old lady dropped it into the ocean in the end…”
That unforgettable line from Titanic made the world fall in love with the legendary blue diamond — the Heart of the Ocean.
Though fictional, it captured a universal truth: diamonds aren’t always colourless.
Yes, diamonds come in colours — rare, radiant hues that nature painted deep within the earth’s heart.
From romantic pinks and fiery oranges to mysterious blues and ethereal greens, coloured diamonds are among the rarest treasures known to humankind.
At Zorba Diamond, we celebrate these marvels of nature — where science, beauty, and rarity unite in a symphony of light.
💠 Colourless or Coloured — Which Is More Valuable?
Most people associate diamonds with icy white brilliance — and indeed, colourless diamonds (graded D to F) are prized for their purity and sparkle.
But when nature gifts a diamond with colour — be it blue, pink, or red — it becomes extraordinarily rare.
In fact, only 1 in 10,000 diamonds mined worldwide displays a natural fancy colour.
Their scarcity, combined with global fascination and celebrity influence, makes them more valuable than their colourless counterparts.
💬 Zorba Insight: In coloured diamonds, intensity of hue matters more than size or clarity. The deeper and more vivid the colour, the rarer — and more coveted — the stone.
🌈 Why Do Diamonds Have Colour?
Every diamond begins as pure carbon, but nature loves imperfection.
When trace elements or environmental forces alter the crystal structure, colour emerges.
Scientists classify diamonds by how these factors occur — forming three main types:
Type I Diamonds — The Element Effect
The most common coloured diamonds, Type I gems owe their hue to trace elements:
- Nitrogen → Yellow or orange tones
- Nitrogen variations → Pink, brown, or green hues
Nearly 98% of all coloured diamonds are Type I — nature’s subtle chemistry at play.
Type II Diamonds — The Purest Rarities
Type II diamonds contain almost no nitrogen and make up just 2% of the world’s supply.
They divide into:
- Type IIa: Exceptionally pure diamonds, often pink, brown, or perfectly colourless.
- Type IIb: Infused with trace boron, giving rise to legendary blue diamonds — such as the world-famous Hope Diamond.
💬 Zorba Fact: Type IIb diamonds can conduct electricity — a phenomenon exclusive to this rare blue variety.
Type III Diamonds — Nature’s Mystery
Some diamonds derive colour from natural radiation or crystal irregularities.
These are known as Type III diamonds, with green diamonds being the most famous example — stones kissed by the earth’s own radiation over millions of years.
🌍 Where Do Coloured Diamonds Come From?
The origins of fancy colour diamonds are as fascinating as their hues:
- India (Golkonda): Historically the cradle of the world’s most enchanting blue diamonds — including the Hope Diamond.
- Australia (Argyle Mine): Source of over 90% of the world’s pink diamonds, each one a marvel of rarity.
- Africa: Home to vibrant orange “fire” diamonds, found in South Africa and the Congo.
- Russia: Known for exquisite purple and violet diamonds from the Siberian mines.
💬 Zorba Insight: With the Argyle Mine’s closure in 2020, natural pink diamonds have become even rarer — and more sought after than ever before.
🎨 The Science of Colour: How Diamonds Are Graded
Just like colourless diamonds use the D–Z scale, fancy coloured diamonds are graded on three main aspects:
1. Base Colour
The diamond’s dominant hue — one of twelve recognised shades:
💎 Red, Orange, Yellow, Green, Blue, Pink, Purple, Brown, Violet, Grey, Black, and White.
2. Colour Intensity
This determines the vividness or strength of the hue — the most critical value factor.
The GIA identifies nine intensity levels:
Faint → Very Light → Light → Fancy Light → Fancy → Fancy Intense → Fancy Vivid → Fancy Deep → Fancy Dark
💬 Zorba Tip: “Fancy Vivid” is the most prized grade — pure, strong colour with breathtaking luminosity.
3. Secondary Colours
Many coloured diamonds exhibit blended tones — creating mesmerising combinations like:
- Purplish Pink
- Orange-Red
- Bluish Green
- Yellowish Grey-Green
The dominant colour is always listed last.
For example, a blue-green diamond is primarily green with a blue tint.
✨ How Coloured Diamonds Are Cut
Unlike colourless diamonds (where brilliance is key), coloured diamonds are cut to maximise colour intensity, not sparkle.
Thus, round brilliant cuts are rare for fancy colours — they tend to dilute the hue.
Instead, expert cutters favour:
- Cushion
- Oval
- Pear
- Radiant
- Emerald
Each cut is strategically designed to enhance face-up colour, making the gem appear richer and deeper in tone.
💬 Zorba Fact: A cushion-cut yellow diamond can appear one full grade higher in colour intensity compared to the same stone in a round cut.
💎 Zorba Diamond Promise: A Symphony of Colour and Light
At Zorba Diamond, every coloured diamond tells a story — of rarity, wonder, and craftsmanship.
Our gem experts meticulously grade and source each fancy colour stone based on global standards from GIA, IGI, and SGL, ensuring authenticity, origin, and brilliance.
Whether it’s the blush of a pink diamond, the serenity of blue, or the mystery of green — each colour holds emotion, elegance, and eternal value.

There’s something timeless about a diamond ring.
Whether it marks an engagement, an anniversary, or a personal milestone, a diamond has the power to make every moment unforgettable. It’s more than jewellery — it’s a promise, a memory, a sparkle that stays with you for life.
But while the beauty of a diamond is eternal, not every stone you see in the market tells the same story. With the growing number of imitation stones and lookalikes, knowing how to buy a diamond ring wisely is just as important as choosing the right design.
At Zorba Diamond, we believe your diamond-buying journey should be filled with excitement — not uncertainty. Here’s your essential guide to buying a genuine diamond ring without getting misled.
💠 Step 1: Know the Basics — The 4Cs of a Diamond
Before you step into any jewellery store (or browse online), you should understand the universal language of diamonds — the 4Cs: Cut, Colour, Clarity, and Carat.
These four characteristics define a diamond’s beauty, brilliance, and value.
Cut – The Sparkle Factor
The cut determines how well a diamond reflects light.
Even a flawless diamond will look dull if it’s poorly cut, while a well-cut diamond will appear radiant and full of life.
Certain cuts, like marquise or princess, also make the stone look larger than it actually is.
Colour – The Tone of Purity
Diamonds are graded from D (colourless) to Z (light yellow or brown).
The closer the grade is to D, the rarer and more valuable the stone.
However, a near-colourless diamond (G–H range) often looks just as stunning — and is more budget-friendly.
Clarity – The Inner World
Clarity measures the presence of natural inclusions or blemishes.
Diamonds with fewer inclusions are clearer and more brilliant.
Grades range from Flawless (FL) to Included (I), with VS and SI being popular for their perfect balance between quality and value.
Carat – The Weight of Beauty
Carat refers to a diamond’s weight — not its size.
Larger diamonds are rarer, hence pricier, but remember: two diamonds of the same carat can vary in value depending on their cut, colour, and clarity.
💬 Zorba Tip: Always prioritise cut quality over carat size — brilliance beats bulk every time.
💎 Step 2: Always Ask for Certification
A diamond’s sparkle may attract your eye, but its certificate should win your trust.
Every authentic diamond should come with a grading report from a recognised gemological laboratory such as GIA, IGI, GSI, or SGL.
This certificate verifies that your diamond has been independently tested for its 4Cs — and protects you from counterfeit or treated stones.
If a jeweller cannot provide certification, it’s best to walk away.
💬 Zorba Promise: Every Zorba Diamond ring comes with a certified grading report — because transparency is the truest form of luxury.
💎 Step 3: Choose a Jeweller You Can Trust
With the rise of online jewellery platforms, diamonds have become easier to purchase — but also easier to fake.
When buying a diamond ring, always choose a reputed jeweller known for credibility and craftsmanship.
Here’s what to look for:
- Years of experience and industry reputation
- Positive customer reviews and verified testimonials
- Clear exchange, return, and refund policies
- Proof of certification for every diamond sold
Avoid buying from unknown sources that lure you with deep discounts or unclear authenticity claims.
A true jeweller sells trust as much as sparkle — and Zorba Diamond stands for both.
💎 Step 4: Simple Tests to Identify Real Diamonds
While certification is your best guarantee, there are a few at-home tests that can help you identify authenticity:
1. The Fog (Breath) Test
Gently breathe on the stone.
If it’s a real diamond, the fog will vanish almost instantly — diamonds disperse heat quickly.
A fake or synthetic stone will stay fogged for a few seconds longer.
💬 Note: Moissanite, a diamond simulant, may pass this test — but it reflects light differently under magnification.
2. The Sandpaper Test
Diamonds are the hardest natural material on Earth.
If you lightly rub sandpaper across a real diamond, it will stay unscratched — but a fake stone will show marks immediately.
This test, however, should be done with extreme care and preferably by professionals.
💎 Step 5: Look Beyond Price Tags
A “deal that sounds too good to be true” probably is.
Extremely low-priced diamond rings may feature synthetic or treated stones that imitate natural ones.
Always evaluate value, not just cost.
💬 Zorba Tip: A genuine diamond holds its brilliance — and its worth — forever. A cheap imitation fades in both.
💎 Final Word — Buy with Knowledge, Wear with Confidence
A diamond ring is a symbol of trust, emotion, and eternity — but only when you know what you’re buying.
By learning the 4Cs, checking certifications, and purchasing from reputed jewellers, you ensure your diamond’s story is as authentic as your own.
At Zorba Diamond, we stand for integrity, artistry, and education — so every sparkle you wear carries the glow of confidence.

💎 Zorba Diamond Guide:
How to Choose the Perfect Solitaire
When someone says solitaire, the image that instantly comes to mind is usually that of a breathtaking diamond ring — timeless, elegant, and deeply personal.
A solitaire isn’t just a jewel; it’s an emotion — a symbol of singular beauty that stands on its own. Whether gracing a ring, pendant, or a pair of earrings, a solitaire is the purest expression of brilliance and simplicity.
But as dazzling as a solitaire looks, choosing the right one requires care, understanding, and a bit of knowledge.
At Zorba Diamond, we believe every solitaire should reflect not only your style but also your confidence. Here’s how you can choose your perfect one — wisely, beautifully, and without doubt.
💠 What Exactly Is a Solitaire?
In simple terms, a solitaire refers to a single diamond or gemstone mounted alone, without any accompanying stones.
It’s not the shape or cut that defines it — it’s the singularity. The entire design is meant to celebrate that one, magnificent stone.
While solitaire diamond rings are the most iconic, they’re not the only choice.
Solitaire pendants, earrings, and even nose pins capture the same understated luxury — one stone, infinite impact.
💬 Zorba Insight: The magic of a solitaire lies in its minimalism. There’s nowhere for the diamond to hide — only pure, visible brilliance.
💎 The 4Cs: Your Compass for Choosing a Solitaire
Before you buy your solitaire, understanding the 4Cs — Cut, Colour, Clarity, and Carat — is essential.
These four attributes define a diamond’s quality, value, and personality.
✂️ 1. Cut – The Secret to Its Sparkle
The cut determines how well the diamond interacts with light — it’s what gives your solitaire its brilliance and fire.
A perfectly cut diamond reflects light beautifully, appearing lively and radiant, while a poorly cut one can look lifeless.
Popular cuts include round brilliant, oval, marquise, cushion, princess, and emerald.
Round brilliants are known for unmatched sparkle, while shapes like oval or marquise often appear larger than their actual weight — a clever way to maximise size visually.
💬 Zorba Tip: Always prioritise cut over carat. A smaller, well-cut diamond will outshine a larger, poorly cut one.
🎨 2. Colour – The Shade of Perfection
Diamonds occur naturally in varying hues, from colourless to faint yellow or brown.
The closer a diamond is to colourless (graded D on the GIA scale), the rarer and more valuable it is.
If you’re looking for high brilliance, aim for grades between D and G. For warmer tones, especially when set in yellow gold, even an H or I diamond can look stunning.
💬 Zorba Insight: A colourless diamond complements white metals like platinum and white gold, while slightly tinted stones glow beautifully in yellow or rose gold.
🔍 3. Clarity – The Purity Within
Clarity refers to the tiny natural inclusions or blemishes inside a diamond.
Most diamonds have them — they’re nature’s birthmarks.
Fewer inclusions mean greater clarity, brilliance, and price.
Grades range from Flawless (FL) to Included (I3).
For solitaires, VS (Very Slightly Included) or SI (Slightly Included) grades offer excellent value — they appear flawless to the naked eye.
⚖️ 4. Carat – The Measure of Weight, Not Beauty
A diamond’s weight is measured in carats, where one carat equals 0.2 grams.
Larger carat weight generally increases the price — but remember, two diamonds of equal carat weight can look different depending on their cut and shape.
💬 Zorba Tip: Focus first on brilliance (cut), then on colour and clarity — and let carat be the final choice that fits your style and budget.
💎 Common Mistakes to Avoid When Buying a Solitaire
Buying a solitaire is a significant investment, and a few common mistakes can make all the difference.
Here’s what to avoid:
🚫 1. Skipping Research
Never rush your purchase. Learn about the 4Cs, set your budget, and decide your priorities.
Would you prefer size over clarity? Colour over carat?
Knowing what matters most to you will help you make a confident decision.
🧾 2. Ignoring Certification
Always, always buy a certified diamond.
A certificate from a recognised lab like GIA, IGI, SGL, or GSI verifies the diamond’s authenticity and quality.
It’s your assurance that you’re paying for what you’re getting — no surprises later.
💬 Zorba Promise: Every Zorba solitaire is accompanied by a certified grading report — your guarantee of purity, precision, and trust.
🏪 3. Buying from Unknown Retailers
Your jeweller should be as trustworthy as your diamond.
Choose only reputed retailers with transparent policies, positive customer reviews, and a proven track record.
Avoid suspiciously low-priced offers or vague product details — true brilliance comes with accountability.
If you’re buying online, ensure the jeweller provides high-resolution product images, certification details, and clear return policies.
💎 Final Thoughts — The Zorba Way to Choose a Solitaire
A solitaire isn’t just jewellery — it’s a story told through light.
When you understand what makes a diamond truly exceptional, you not only choose a stone, you choose confidence.
So take your time, learn the 4Cs, ask the right questions, and buy from a brand that values integrity as much as sparkle.
At Zorba Diamond, we believe every solitaire should reflect your individuality, your emotion, and your trust.
💬 Zorba Diamond — Because true brilliance needs no company.
8. Zorba Diamond Guide: How to Tell if a Diamond is Real or Fake
Elizabeth Taylor once said, “You can’t possess radiance, you can only admire it.”
At Zorba Diamond, we believe true radiance begins with authenticity. Diamonds have a magic that captivates everyone — their light, their brilliance, their timeless charm. But in today’s market, imitation stones often attempt to mimic this perfection, leaving buyers vulnerable to costly mistakes.
So, how do you tell whether your diamond is genuine or not?
The good news is, you don’t need to be a gemologist to identify the difference. With a few simple observations and tests, you can protect yourself from being deceived and ensure that the sparkle you adore is truly worth its brilliance.
💠 1. The Fog Test (Also Known as the Breath Test)
This simple test can quickly reveal the truth behind your diamond’s shine.
Hold the diamond close to your mouth and gently exhale on it — just as you would fog up a mirror.
Because real diamonds disperse heat almost instantly, the fog will disappear immediately.
If the mist lingers for three to four seconds, the stone likely isn’t real.
💬 Zorba Tip: Conduct this test only after gently cleaning the stone to remove dirt or oil, which can affect results.
🔍 2. The Loupe Test – A Glimpse Into the Stone
A loupe is a small magnifying lens used by jewellers to inspect diamonds up close.
When you examine your diamond under a loupe, look for tiny imperfections or inclusions — these are natural characteristics found in real diamonds.
However, don’t be alarmed if your diamond looks flawless — lab-grown diamonds are also real but tend to have fewer inclusions.
This test simply helps you differentiate between natural, lab-grown, and synthetic imitation stones.
💬 Zorba Insight: Every natural diamond tells its story through its inclusions — they are nature’s own signature.
💎 3. The Water Test (For Loose Diamonds)
If you have an unmounted diamond, the water test is one of the easiest ways to check its authenticity.
Fill a glass with water and gently drop the diamond into it.
A genuine diamond will sink to the bottom due to its high density, while a fake or low-density imitation will float or hover near the surface.
💬 Note: This test is indicative, not conclusive. Some imitations may also sink, so use it in combination with other checks.
🔥 4. The Fire Test – Strength Under Pressure
Diamonds are known for their ability to withstand extreme heat.
To test this, carefully heat the stone over a candle flame for about 30 seconds, then immediately drop it into cold water.
A real diamond will remain unaffected, while most fakes will crack or shatter due to thermal shock.
💬 Caution: Perform this test only on loose stones and never on mounted jewellery.
🌈 5. The Refractivity Test – Light Tells the Truth
Real diamonds bend (refract) light sharply, creating that signature sparkle known as fire.
You can check this at home with two simple methods:
• The Newspaper Test
Place the diamond upside down on a newspaper page.
If you can clearly read the letters through the stone or see the print beneath it, your diamond is likely fake.
A genuine diamond’s refraction scatters light, making it nearly impossible to see through.
• The Dot Test
Draw a small dot on a white sheet of paper. Place your diamond directly over it.
If the dot is visible or reflected inside the stone, it’s not a real diamond.
If the dot disappears completely — congratulations, your diamond passes this test!
💍 6. Check the Metal and Mount
A genuine diamond is rarely set in low-quality metal.
Inspect the inner band of your jewellery — markings such as “10K,” “14K,” “18K,” “PT,” or “PLAT” indicate gold or platinum settings, which typically hold real diamonds.
If you notice a “C.Z.” (Cubic Zirconia) stamp or no hallmark at all, the diamond may not be authentic.
💬 Zorba Tip: Genuine craftsmanship always comes with certified materials. At Zorba Diamond, every piece carries both hallmark and authenticity certification.
⚖️ What If Your Diamond Fails a Test?
If your diamond fails one or more of these checks, don’t panic just yet.
Run a few additional tests to confirm your observations. Some imitations may pass one test but fail another.
However, if your diamond consistently fails multiple tests, it’s best to consult a certified gemologist for professional verification.
They use advanced tools such as thermal conductivity probes and spectroscopic analysis to determine authenticity beyond any doubt.
💎 How to Ensure You Always Buy Real Diamonds
The best way to avoid uncertainty is to be proactive at the time of purchase:
- Buy only from trusted, reputed jewellers who have an established legacy of quality and transparency.
- Ask for certification from recognized laboratories such as GIA, IGI, GSI, or SGL. This certification ensures your diamond’s authenticity and grades it for the 4Cs — Cut, Colour, Clarity, and Carat.
💬 Zorba Promise: Every diamond from Zorba Diamond comes with independent certification and lifetime authenticity assurance — so your sparkle is as real as your trust.
💫 Final Thought – Real Brilliance Can’t Be Faked
In a world full of imitations, authenticity shines brightest.
A real diamond doesn’t just reflect light — it reflects legacy, emotion, and truth.
So the next time you buy or receive a diamond, let knowledge guide your admiration.
Because when you hold a genuine diamond, you don’t just wear luxury — you wear a piece of eternity.

9. Is Buying Diamond Jewellery a Smart Investment in Today’sEra?
For generations, the word “investment” meant one thing — pure gold. Families relied on it for financial security, wealth preservation, and legacy. Diamonds, though admired for their brilliance, were often viewed merely as adornments, not assets.
But times have changed — and so has the mindset of the modern investor.
Today, the luxury-conscious generation seeks beauty with value, art with appreciation, and fashion with financial foresight. This is where diamonds have found their new identity — not just as symbols of love, but as symbols of intelligent investment.
At Zorba Diamond, we believe that a well-chosen diamond is not an expense — it’s a timeless asset.
✨ The Modern Edge: Why Diamond Jewellery Makes Financial Sense
1. Compact Wealth
Diamonds concentrate value like few other assets.
A small solitaire can hold the worth of a gold bar — and yet rest effortlessly in your palm.
Their high value-to-volume ratio makes them ideal for discreet, portable, and long-term storage of wealth.
2. Wearable Asset
Unlike traditional investments locked in vaults or on paper, diamond jewellery lets you wear your investment.
Each pendant, ring, or bracelet reflects your taste while silently holding financial worth — a fusion of emotion and economics.
3. Enduring Durability
A diamond is nature’s strongest creation. It doesn’t fade, tarnish, or corrode — ensuring your asset lasts for generations. With minimal care, your diamond retains its brilliance and value indefinitely.
4. Inflation-Resistant Value
As tangible assets, diamonds have historically shown stability against inflation and market volatility. Their rarity and rising global demand continue to keep them a reliable long-term store of value.
⚖️ Understanding the Risks Before You Invest
No investment is without caution, and diamonds are no exception.
1. Market Transparency
Unlike gold, diamond prices don’t follow a daily public index. Their valuation depends on quality grading, certification, and market demand. Always buy from trusted jewellers and certified sources.
2. Limited Liquidity
Selling diamonds may take time — resale markets differ in pricing standards. Treat diamonds as a long-term wealth-holding asset, not a quick-profit commodity.
3. Long-Term Vision
Diamonds reward patience. Their appreciation is steady, not speculative. As part of a diversified portfolio, they offer balance, not instant returns.
