Fancy-Colored Diamonds

What are Fancy Colored Diamonds?

While most diamonds are prized for their pure, colorless beauty, fancy colored diamonds celebrate vivid hues that occur naturally during their formation. From deep blues to fiery oranges, these rare diamonds owe their color to trace elements and unique conditions during their growth.

Unlike traditional diamonds, where less color is more desirable, the opposite is true here — the richer and more vibrant the color, the more valuable the diamond.

How do Fancy Colored Diamonds Get Their Color?

A few popular examples:

Blue diamonds get their color from traces of boron.
Yellow diamonds come from nitrogen impurities.
Pink and red diamonds are believed to be caused by structural distortions.
Green diamonds result from natural radiation during formation.

Every fancy color has its own incredible backstory, making each stone not just a treasure, but a true piece of natural history.

The Rarest of the Rare

True red diamonds are so rare that only a handful exist in the entire world — and each one commands astronomical prices at auction.

How are Fancy Colored Diamonds Graded?

Fancy colored diamonds are graded based on three key aspects of their color: hue, tone, and saturation.

Hue is the diamond's primary color, such as blue, yellow, pink, or green. Some diamonds can also have modifying secondary hues that influence their overall appearance (for example, a diamond could be purplish-pink or greenish-blue).
Tone refers to how light or dark the color appears. A diamond with a lighter tone will look softer and brighter, while a darker tone will create a deeper, richer appearance.
Saturation is the intensity or strength of the color. Diamonds with vivid saturation have the most powerful, pure colors and are considered the most valuable.

These three elements — hue, tone, and saturation — together determine how a fancy colored diamond is described and valued.
Unlike colorless diamonds, where a lack of color is ideal, here the stronger and more vivid the color, the more desirable the diamond becomes.

A History Painted in Color

In ancient India, colored diamonds were revered not just for their beauty, but believed to carry mystical powers tied to their specific hues.

How Color Affects Value

In fancy colored diamonds, color is the most important factor in determining value — much more than cut, clarity, or even carat weight.

Diamonds with vivid and pure hues (like "Fancy Vivid Blue" or "Fancy Vivid Pink") command the highest prices.
Rare hues (like blue, green, red, and pink) are valued far more than more common colors like brown or gray.
Secondary hues (like brownish-pink or greenish-blue) can affect desirability depending on how they enhance or detract from the primary color.

How Size (Carat) Affects Appearance and Price

Larger fancy colored diamonds are extremely rare, especially if the color saturation remains strong at higher carat weights.

Because color is key, even a smaller fancy colored diamond with superb saturation can be more expensive than a bigger but lighter-colored diamond.

More Precious than White

While white diamonds are more commonly associated with classic beauty, some fancy colored diamonds — especially vivid pinks and blues — can be ten to fifty times more valuable than a similar-sized colorless diamond.

Why are Fancy Colored Diamonds Rare?

Natural fancy colored diamonds are incredibly rare — especially certain colors like vivid pinks, blues, and greens. For every tens of thousands of traditional white diamonds mined, only a handful of fancy colored ones are found.

This rarity, combined with their mesmerizing colors, makes them highly sought after by collectors, investors, and those who want something truly one-of-a-kind.

Are fancy colored diamonds natural?

Yes — many fancy colored diamonds occur naturally due to trace elements or structural distortions during their formation. Some colors, like blue or pink, are incredibly rare in nature.

What's the most expensive fancy diamond color?

Historically, red diamonds are the rarest and most expensive, followed by vivid blues and vivid pinks. Even very small red diamonds can fetch astronomical prices.

Are fancy colored diamonds a good investment?

Many collectors and investors view natural fancy colored diamonds as a strong long-term investment, especially rare colors like pinks and blues. However, as with all investments, it’s important to buy carefully and consult experts.

What should i look for when buying fancy colored diamonds?

Color is the most important factor, followed by carat size and cut. Clarity matters less as long as the color is beautiful. Focus on finding a strong, pure color you love.
