What Are the Rarest Diamonds
Aside from exquisite beauty, what makes Fancy Color Diamonds so incredibly unique is how rare these precious gems actually are. There are a small number of diamond mines throughout the world that are known for the unique colors they manage to produce.
However, of diamonds already so scarce, there are a few colors which are so rarely found that the singular stones in the market are highly sought after by collectors and diamond enthusiasts.
There are only 12 different colored diamonds. However, as a result of 9 different intensity levels, 90 secondary hues, over 230 color combinations, and the various options of sizes, clarity, and cut – the different types of colored diamonds available are endless. Even still, Fancy Color Diamonds only represent less than 0.1% of all colorless diamonds produced each year!

The Most Common Colors
Without any doubt, both Yellow diamonds and Pink diamonds have the highest market demand, even though there is a large price difference between the two. As a result to the abundance of Yellow diamonds found, they are a lot less expensive per carat than Pink stones. Interestingly enough, depending on the color intensity, many yellow diamonds are less expensive than their colorless counterparts.

More than the popular colored stones, there are a number of selected color diamonds which are considered so scarce, that the sale is often secure with a client before the diamond even arrives at the company’s headquarters. Furthermore, the price tag attached, obviously depending on the diamond characteristics, can sometimes reach hundreds of thousands of dollars or more.
Rarest Colors in the World
Some of the most magical diamonds are often purchased from major auction houses like Sotheby’s and Christie’s. However, there are a number of fancy color diamond dealers where these unique pieces can sometimes be sourced. Still, even from these companies it isn’t every day that the rarest colors pass through their inventory. So what are the rarest colored diamonds?
Of the various different colors, Fancy Red Diamonds are by far the rarest. They are not often found, and sourced from very few locations around the world.

Contrary to other colors, it is almost impossible to identify if any type of artificial enhancement was done on a Green diamonds in order to enhance the color.
