Lazurite Afgan Extra class

Lazurite (Lapis Lazuli) Afgan Extra class natural pigment powder.

Lazurite is a relatively rare semi-precious stone that has been prized for its deep blue color since ancient times. It has been mined in Afghanistan for over 8000 years, and in Russia since the 19th century. 

Extra class Lazurite differs from other types in its deep and intense blue color. This color is achieved through manual sorting of raw materials (stones), and 3-stage cleaning, which also includes a flotation process.
