Opale Verte

Green opalite is found in a desert in the Western USA. Deriving from an Iron (ll) compound, the pigment’s green color is very intense since the shiny, slightly light-breaking raw material is of pure quality. One can describe opalite as a silicate compound which could possibly transform to opal after many million years. Green opalite belongs to the chemical group of glauconites. The stones are ground to a powder finer than 63 µ.
