Buying a diamond should feel exciting, not confusing. Yet many Perth buyers quickly run into terms like D colour, near colourless, fancy yellow, lab-grown pink, or champagne diamond without a clear explanation of what those words actually mean.
The truth is simple: diamond colour can mean two different things.
- Colour grade – how colourless a white diamond is
- Actual colour – diamonds that naturally appear yellow, pink, blue, black, champagne and more
Both matter. Both affect price. Both influence style.
This guide explains diamond colours properly, for those who want reliable information before making an important purchase.
What Does Diamond Colour Mean?
When jewellers discuss colour, they may be talking about either:
1. White Diamond Colour Grade
This measures how little colour a white diamond has. The less visible the tint, the higher the grade.
2. Fancy Diamond Colour
These diamonds display natural body colour such as pink, yellow, blue, green, black, or champagne.
These are graded differently from white diamonds.
Understanding this distinction helps buyers avoid one of the most common sources of confusion.
White Diamond Colour Grades (D to Z)
Gemological Institute of America uses the most recognised grading scale and ranges from D to Z.
D-F: Colourless
Rare, bright white, premium priced.
Best for:
- Buyers seeking top specifications
- White gold or platinum rings
- Prestige purchases
G-H: Near Colourless
Often the smartest balance of beauty and value.
Best for:
- Engagement rings
- Practical buyers
- Most Perth customers want a white look without overpaying
I-J: Slight Warmth
May show subtle warmth depending on shape and setting.
Best for:
- Yellow gold rings
- Vintage styles
- Buyers prioritising carat size
K-Z: Visible Tint
Increasingly warm tones become visible.
Best for:
- Budget-driven purchases
- Specific antique aesthetic
Can You See the Difference Between Grades?
Sometimes yes, but context matters.
Side-by-side under jewellery lighting, differences may be easier to notice. Once mounted in a ring and worn normally, many people struggle to tell small grade jumps apart.
For many buyers:
- G and H look excellent
- F and G often appear very similar
- Paying extra for D may not create an obvious everyday benefit
That is why many experienced buyers prioritise cut quality before chasing the top colour grade.
Fancy Coloured Diamonds Explained
Fancy coloured diamonds are valued for their natural colour presence rather than lack of colour.
They are graded by hue, tone, and intensity, not the D-Z white scale.
Common intensity terms include:
- Fancy Light
- Fancy
- Fancy Intense
- Fancy Vivid
- Fancy Deep
The stronger and purer the colour, the rarer the diamond often becomes.
Popular Natural Diamond Colours

Among the more accessible fancy colours.
Popular for:
- Statement jewellery

Pink Diamonds
One of the world’s most admired diamond colours.
Western Australia became globally famous through the Argyle Diamond Mine, historically known for rare pink diamonds.
Popular for:
- Luxury collectors
- Heirloom jewellery
- Rare investment-minded purchases
Blue Diamonds
Very rare and highly prized.
Known for elegance and strong collector demand.

Why Diamond Colour Matters?
Perth buyers often look for a practical balance of:
- Appearance
- Long-term enjoyment
- Budget discipline
- Distinctive design
That means not everyone wants the highest white grade. Some buyers prefer:
- Larger near-colourless diamonds
- Champagne diamonds with character
- Lab-grown high-colour stones
- Rare pink-accent jewellery
Natural vs Lab-Grown Diamond Colours
Both natural and lab-grown diamonds can be graded by respected laboratories such as the Gemological Institute of America and the International Gemological Institute.
That means:
- Natural diamonds can be D colour
- Lab-grown diamonds can be D colour
- Both can also be produced or found in fancy colours
Main Differences Buyers Notice
Natural Diamonds
- Formed over geological time
- Often chosen for rarity and natural origin
- Strong emotional and heirloom appeal
Lab-Grown Diamonds
- Higher colour grades often more affordable
- Larger sizes are possible for the same budget
- Popular with value-focused buyers
Neither category is automatically “better.” It depends on your priorities.
Lab-Grown Fancy Colours
Lab-grown technology has increased access to coloured diamonds such as:
- Pink
- Blue
- Yellow
These options can offer the look of rare colour at a lower entry price than natural fancy-coloured stones.
For style-focused buyers, they can be worth exploring.
Best White Diamond Colour by Shape
Diamond shape influences how colour appears.
Round Brilliant
Excellent at hiding colour due to sparkle.

- Natural: G-H
- Lab-grown: F-G
Oval / Pear / Marquise
Can show warmth more clearly at tips.
Recommended:
- Natural: F-G-H
- Lab-grown: D-F
Emerald / Asscher
Large open facets reveal colour more easily.
Recommended:
- Natural: F-G
- Lab-grown: D-F
Best Colour by Metal Type
White Gold / Platinum
Enhances white appearance but may reveal warmth sooner.
Recommended:

Popular Diamond Colour Choices in Perth (2026)
White Diamonds
Still the leading choice for engagement rings.
Most practical ranges:
- Natural G-H-I
- Lab-grown D-F-G
Champagne Diamonds
Well-liked in Australia for individuality and warmth.
Pink Accent Stones
Used in halo rings, dress rings, or collector pieces.
Black Diamonds
Modern masculine or alternative styling.
Is D Colour Worth It?
Sometimes—but not always.
D colour diamonds are premium and rare in white categories. However, many buyers are equally satisfied with F, G, or H once the diamond is mounted.
If budget matters, choosing:
- Slightly lower colour
- Better cut quality
- Better setting craftsmanship
often creates stronger real-world satisfaction.
Common Buying Mistakes
1. Chasing Paper Grades Only
Numbers matter, but visual beauty matters too.
2. Ignoring Shape Impact
Oval and emerald cuts reveal colour differently than round stones.
3. Overpaying for Invisible Upgrades
Small jumps can cost more than they visibly deliver.
4. Forgetting Lifestyle
A ring should suit daily wear, taste, and budget comfort.
5. Assuming All Fancy Colours Are Equal
Intensity, origin, and rarity vary greatly.
