When people talk about diamonds, most of them will first think of classic colorless diamonds. But nature creates many stunning colored stones too. They are widely know as fancy color diamonds. These colored diamonds are extremely rare and one of a kind. Their value mostly depends on how rare their color is. So which fancy color diamonds are the hardest to find in the world?
First, let’s learn why diamonds get their color. Pure colorless diamonds are made of only carbon. Fancy color diamonds get their hues from small changes during their formation deep underground. There are three main reasons.
First is chemical impurities. For example, nitrogen turns diamonds yellow, and boron creates blue color. Second is structure defects. Twisted crystal lattice can make diamonds pink, red or brown. Third is natural radiation. This special effect forms green diamonds.
The rarest natural fancy color diamond in the world is red diamond. Below is the ranking of top rare colored diamonds, sorted by rarity, with simple explainations.
Extremely Rare：
Red Diamond
Red diamond is the king of all rare diamonds. It is no doubt the rarest one on earth. People still not fully understand how it gets its vivid red color. Most experts believe it is caused by plastic deformation during crystal growth. This tiny defect at atomic level absorbs certain light, and finally shows bright red.
Almost no pure red diamonds exist. Most red stones come with secondary tones, like purple, orange or brown. Only a few pure red diamonds have ever appeared on the open market. The most famous one is the Moussaieff Red, which weights 5.11 carats.
Blue Diamond
We are talking about vivid fancy blue diamonds here. Its color comes from the trace element boron. Boron hardly combines with carbon deep in the earth’s mantle. That is why natural blue diamonds form under very harsh conditions. Two world-famous examples are the Hope Diamond and the 14.62-carat Oppenheimer Blue.
Pink Diamond

Pink diamonds are beautiful and incredibly rare. Different from blue diamonds, their color does not come from impurities. Extreme pressure twists the carbon lattice and causes plastic deformation. This changes how light is absorbed and creates soft pink tones. The Argyle Mine in Australia was once the main source of pink diamonds. It closed in 2020, so pink diamonds become even harder to find today. The 59.60-carat CTF Pink Star is the most iconic pink diamond, and it sold for an amazing price at auction.
Moderately Rare：
Green Diamond
Natural green diamonds get their color from long time exposure to natural radiation. Real fancy vivid green diamonds are super rare. Most green color only stays on the stone’s surface. If cutters remove the colored part during polishing, the diamond will lost most of its value. The 41-carat Dresden Green is the most well-known green diamond.
Purple Diamond
Purple diamonds are unusual and rare. Their color is a mix of plastic deformation and hydrogen impurities. Pure purple diamonds are hard to find. Most have pink or grey overtones.
Orange Diamond
Pure bright orange is also called flame color. It is extremely scarce. The color is formed by both nitrogen and crystal structure flaws. Pure orange diamonds are even rarer than pink ones. Most orange diamonds on market carry brown or yellow shades. The 5.54-carat Pumpkin Diamond is its top representative.
Relatively Rare：
Yellow Diamond
Yellow diamonds are the most common fancy color diamonds. Even so, Fancy Vivid Yellow stones are still rare and valuable. Nitrogen is what gives them yellow color. Pale yellow or brownish yellow diamonds are easy to see. But saturated, bright canary yellow diamonds are worth a fortune. The 128.54-carat Tiffany Yellow Diamond is a world-famous treasure.
The world of diamonds is more than just colorless stones. From deep red to bright blue, every fancy color diamond is a unique miracle made by nature.
