SEARCH NATURAL FANCY BLACK COLORED DIAMONDS
Colored diamonds — also known as “fancy diamonds” — are a rare and captivating type of natural diamond that appear in an incredible range of hues. In the diamond world, rarity often determines value, and fancy colored diamonds are far less common than traditional white diamonds.
Only about one in every 10,000 diamonds naturally forms with a fancy color, making them some of the most prized and sought-after gemstones on the market. These diamonds occur in a variety of shades — from popular pinks and yellows to extremely rare blues, greens, oranges, and purples.
Unlike colorless diamonds, which are valued for their lack of color (graded on the GIA’s D-to-Z scale), fancy colored diamonds increase in value as the intensity and vibrancy of their color deepen. These diamonds fall outside the Z scale, with the most vivid examples being especially rare and valuable.
There are 12 primary color categories, over 90 secondary hues, nine intensity levels, and more than 230 possible color combinations. Many fancy diamonds feature blended or muted tones due to secondary colors like gray, brown, or orange. The most desirable stones are those with strong, vivid color saturation and minimal dilution.
Among these, natural fancy black diamonds stand out for their bold, opaque appearance and mysterious allure. While technically more available than pink or blue diamonds, high-quality natural black diamonds are unique, elegant, and luxurious in their own right.
One of the most iconic black diamonds in history is the “Black Orlov,” also known as the “Eye of Brahma” — a legendary 67.50-carat cushion-cut diamond shrouded in intrigue.
BLACK DIAMONDS
Fancy black diamonds are unlike any other colored diamond. Rather than getting their color from trace elements like nitrogen or boron, they owe their dark appearance to thousands of tiny natural inclusions — most often graphite — that absorb light and give the stone its rich, inky tone.
Unlike most diamonds, which reflect light for brilliance and sparkle, black diamonds have a striking mirror-like finish and dramatic, glossy surface. Their bold and sophisticated look has made them a popular choice for statement jewelry and modern engagement rings.
While more abundant than some rare colors, large, well-cut, naturally colored black diamonds remain highly sought after. They’re especially admired in contemporary jewelry designs, where their contrast and edge stand out.
GRADING NATURAL FANCY COLORED DIAMONDS
Grading fancy colored diamonds is a specialized process due to the range of hues and intensities. The Gemological Institute of America (GIA) is the leading authority in diamond grading and uses both visual comparisons and reference stones to determine color characteristics.
Unlike white diamonds, which are evaluated based on the absence of color, fancy diamonds are graded for their hue and saturation. However, the standard GIA intensity scale (ranging from Faint to Fancy Deep) usually doesn’t apply to black diamonds. Instead, black diamonds are assessed based on:
- Whether the color is natural or treated
- Evenness of color throughout the stone
- Surface quality and polish
- Overall visual impact
At Rêve Diamonds, we only offer 100% natural fancy black diamonds, and each stone is GIA or IGI-certified to verify its authenticity and natural color origin.

Frequently Asked Questions About Fancy Black Colored Diamonds
-What is a fancy black diamond?
A fancy black diamond is a natural diamond that appears black due to a high concentration of tiny inclusions — typically graphite — that absorb light and give it a bold, opaque look.
-Are black diamonds natural?
Yes, black diamonds occur naturally, although some are treated to enhance their color. At Rêve Diamonds, we only offer natural black diamonds that are GIA-certified to confirm their untreated origin and authenticity.
-How are black diamonds different from other fancy colored diamonds?
Most fancy diamonds get their color from trace elements like nitrogen or boron. Black diamonds are different — their color comes from dense mineral inclusions. They have a glossy, almost metallic sheen and don't sparkle like white or other colored diamonds.
-Are fancy black diamonds valuable?
Yes. Natural black diamonds are especially valuable when they are large, well-cut, and have consistent color. While typically more accessible than pink or blue diamonds, high-quality black diamonds are still in high demand for their bold and luxurious appearance.
-Are black diamonds a good choice for engagement rings?
Absolutely. Black diamonds are a striking and unconventional option for engagement rings. They pair beautifully with white diamonds or colored stones and look stunning in settings made from white gold, platinum, or rose gold.
-How can I tell if a black diamond is natural or treated?
Always request a GIA certificate. It will confirm whether the diamond is naturally black or has been treated. Since treated black diamonds are common on the market, certification is essential.
-Are black diamonds a good investment?
Natural black diamonds — especially those with even color and no treatments — are becoming increasingly popular among collectors and investors. Their rarity, visual impact, and uniqueness make them a smart long-term choice.
-How should I care for a black diamond?
Black diamonds are durable, but their inclusions can make them slightly more brittle than white diamonds. Clean them gently with a soft brush and mild soap. Avoid ultrasonic cleaners and have your jewelry checked annually by a professional to ensure the setting is secure.

For most fancy colored diamonds, “intensity” refers to how vivid or deep the hue appears — with more intense colors being rarer and more valuable. While black diamonds aren’t graded on this intensity scale, those with consistent, opaque color and minimal surface blemishes are the most desirable.
