Perfectly colorless diamonds are what we typically picture when we think of a diamond. The truth is that you may find colored diamonds in all shapes and sizes, ranging from completely transparent to almost black, with every color in between. Fancy or colored diamonds can be used to create a statement or add some extra flair to a piece of jewelry. Additionally, unlike clear or white diamonds, which are colorless, the higher the saturation, the more precious the diamond. In addition to their remarkable beauty, Fancy Color Diamonds are very rare, which is what makes them so exceptional. Only a few diamond mines in the world are renowned for the distinctive hues they are able to generate.
However, even though diamonds are already so rare, some colors are so hard to come by that collectors and diamond lovers pay top dollar for the unique stones that are available. Only 12 different hues of diamonds exist. However, there are an infinite number of different kinds of coloured diamonds to choose from due to the nine different intensity levels, 90 secondary colors, over 230 color combinations, and numerous size, clarity, and cut options. This article provides information on What is the rarest diamond color.
- Are coloured diamonds a natural occurrence?
All colors are possible for lab-created and naturally occurring diamonds, however natural coloured diamonds are significantly less common. The best-known locations for finding natural fancy diamonds are Australia, South Africa, and India. However, they have also been discovered in Indonesia, Guyana, Brazil, and Venezuela. Due to the makeup of the rocks and soil nearby, different mines throughout the world may generate diamonds that are of varying colors.
- THE RAREST DIAMOND COLOR
- RED DIAMONDS

The precise procedures that give rise to red diamonds are still a mystery. Generally speaking, it is believed that they entail a process known as plastic deformation that warps their molecular structures.
Deep below the earth's surface, where temperatures are exceedingly hot and pressures are incredibly high, plastic deformation occurs. Newly created diamonds are manipulated by powerful forces like dough until some of the exterior atoms escape the lattice and slide to a different row, where they reconnect, resulting in deformations that refract light to appear red. There is a connection between pink and red diamonds. Pink diamonds have always been found alongside red diamonds; red diamonds are not always found with pink ones.
From 1983 until its closure in 2020, the Argyle Mines in rural Kimberley, North-western Australia, produced pink, purple, and red diamonds. Approximately 30 genuine natural red diamonds have been discovered. Even if the red is secondary, prices between two equally-rated red diamonds can vary by up to 60% per carat. They can therefore be 30% to 400% more expensive than the most expensive coloured diamonds.
- Blue Diamonds
There are some disagreements over whether Pink or Blue Diamonds are the second-rarest gems, although it seems like there are more Pink Diamonds on the market.
- The two most well-known blue diamonds in existence are:
- The Hope Diamond: a 45.52 carat, Fancy Deep Grayish-Blue diamond with a VS1 clarity grading.
- The Wittelsbach Graff: a 31.06 carat, Fancy Deep Blue diamond with an IF (internally flawless) clarity grading.
Australia, South Africa, and India are the sources of blue diamonds. They are propelled from the depths of the earth to the surface by tiny volcanoes known as Kimber. They are coloured because of the presence of hydrogen and/or boron.
They are categorized as Type IIb Fancy and range in color from Faint Blue to Fancy Dark Blue, with the majority having an additional tint. A greyish-blue diamond may cost 1/7 as much as an equally weighted Fancy Intense blue diamond. Instead of being electrical insulators, some blue diamonds are electrical semiconductors.
- The costly blue diamonds ever sold at auction included some of the following:
- The extraordinarily unusual Wittelsbach Graff diamond was sold in 2008 for an incredible USD $24.3 million. Approximately $9 million USD was paid in 2009 for a 7.03 carat, flawless blue diamond.
- Green Diamond
Another rarer fancy diamond is green. It can be challenging to determine whether artificial means have been employed to increase the color's intensity. Compared to other colors, which are quite tough to improve, this one is quite different. The Ocean Dream and the Dresden Green Diamond are the most well-known diamonds in this region.
- PINK DIAMONDS
Lacking impurities, pink diamonds get their colour through plastic deformation, as do red diamonds. Pink diamonds have trace nitrogen and boron. They are found in Brazil, South Africa, and Australia. Prices average between $10,000 and $700,000 per carat.
- THE GRAFF PINKTHE PERFECT PINK, a Fancy Intense pink diamond, weighs 14.23 carats. It sold in 2010 at Christie's in Hong Kong for 18,996,100 in US dollars.
- THE STEINMETZ PINK, now known as THE PINK STAR DIAMOND, is the largest known Vivid Pink diamond ever rated, at 59.60 carats. It was bought at $83,187,381 in 2013.
- The rare varieties of colourless diamonds
While colourless diamonds are often more plentiful, coloured diamonds are the rarest of all. The type of formation is important here. The rarest samples of colourless diamonds are Type IIa (also known as 2 A).
Because they are mined in India's Golconda mine, Type IIa diamonds are sometimes known as "Golconda" diamonds. They are characterised by a lack of nitrogen impurities and a lengthy. formation period, which produce the most coveted qualities: D colour and perfect clarity. The coloured diamonds, particularly those with pale blue, green, and pink tints, can also contain IIa type. These jewels are typically the most expensive, purest, and rarest diamonds in the entire world.
