Rublev Colours Lazurite is an intense deep blue color from the precious lapis lazuli stones used in historical painting. It is a semi-transparent, medium-grained color with good tinting strength.
Lapis lazuli or lapis for short is mostly lazurite but commonly contains pyrite, calcite, and other minerals. The name lazurite means "blue rock" and is always a brilliant blue with violet or greenish tints. Small crystals of pyrite are always present in lapis and their golden yellow color distinguishes lapis from a similar mineral, sodalite, and the synthetic pigment, ultramarine. The golden impregnations of pyrite create the impression of stars in a dark blue sky.Composition and Permanence
