Russian Federation

In Siberia, color diamonds are brown, yellow-gray and pinkish-purple. They have an octahedral crystalline structure and usually have a large cleavage (or gletz). The pink stones sometimes have two distinct colors: one part of the stone is brown, and the other is pink. Skilled cutters are able to divide the stone so as to obtain two diamonds, each with its own color.

Types of diamonds produced in Russia:


Siberia: colorless, grayish-yellow, light to intense purple, "brown".

Other mines: yellow.
