However, in addition to the most basic colors, there are 9 more intensity levels that determine the saturation and depth of a diamond's color. From faintly colored to rich and vibrant, these hues make each colored diamond unique and delightful.

In total, there are about 90 different shades of colored diamonds, which makes collecting and studying them endlessly exciting. And each colored diamond, whether rare or exclusive, brings a new dimension of splendor and magic to the world of precious stones.

Red diamond

Red diamonds are the rarest and most valuable of all colored diamonds. They are true rarities of nature and are extremely rare.  Red diamonds are so rare that even experienced jewelers rarely come across them. They make up only about 0.01% of all diamonds mined.

They also have a deep, rich red color, which is the result of boron impurities in their crystal lattice. Red diamonds usually come in small sizes, and those with a large carat weight are considered the most valuable.

They are also one of the most expensive and valuable gemstones in the world. Their price can be significantly higher than the price of other colored diamonds. Among the most famous red diamonds are the Moulin Rouge and the Countess Vronskaya. Because of their rarity and uniqueness, they are a subject of interest for collectors and investors, and their value can reach millions of dollars per carat.

Blue diamond

There is controversy as to whether pink or blue diamonds are the second rarest, however it is clear that pink diamonds are more common in the market compared to blue ones.

Two of the most famous blue diamonds are:

  2. Wittelsbach Graff: Weighs 31.06 carats and is a fancy navy blue with an internally flawless (IF) purity.

Pink diamonds are among the rarest and most valuable in the world. Their limited supply and superior quality make them particularly attractive to collectors and jewelers.

A few examples of rare pink diamonds and their significant value:

Green diamond

Unlike other colors, determining whether a green diamond has been artificially enhanced in any way to improve its color is extremely difficult. As a result, most cutters prefer to keep the girdle portion of a diamond in its natural state without any alteration. This practice is widespread and does not affect the clarity of the diamond.

Here are some examples of rare green diamonds and their significant price:
