DIOPSIDE FOR SALE
Diopside is a pyroxene mineral with the chemical formula MgCaSi₂O₆. It is often found as small green crystals within metamorphic and igneous rocks, though it can vary in color including yellow, brown and black crystals. It is an important indicator rock when searching for deep-source volcanic pipes that may or may not contain diamonds. Geologists that are searching for these pipes often look for diopside crystal fragments since they form in nearly the same atmospheric conditions and locations as diamonds. Diopside crystals with deep green coloration are known as chrome diopside.
