description Diopside Overview
Diopside is a calcium-magnesium silicate mineral in the pyroxene group, with a monoclinic crystal structure and ideal formula CaMgSi2O6. It occurs in igneous and metamorphic rocks and may be white, gray, brown, or green; chromium-rich material forms the transparent green variety known as chrome diopside. Ordinary diopside is mainly of mineralogical interest, while transparent and strongly colored material is cut for jewelry and collected as gem rough or crystals.
help Diopside FAQ
What is diopside?
Diopside is a calcium-magnesium silicate mineral in the pyroxene group. Its ideal chemical formula is CaMgSi2O6, and it has a monoclinic crystal structure.

Diopside can be white, gray, brown, or green. Chromium-rich diopside forms a transparent green variety that is used as a gemstone.
Where does diopside occur?
Diopside occurs in both igneous and metamorphic rocks. Its presence can help describe the mineral conditions under which those rocks formed.
Is chromium diopside the same as ordinary diopside?
Chromium diopside is a green, gem-quality variety of diopside colored by chromium. It still belongs to the same pyroxene mineral species.
