diopsiid
Diopside is a mineral belonging to the pyroxene group, with the chemical formula CaMgSi2O6. It is a common constituent of many igneous and metamorphic rocks, particularly in mafic and ultramafic rocks. Diopside can be found in a variety of colors, including green, yellow, brown, and colorless, depending on the presence of impurities. Gem-quality diopside is often a vivid green.
Crystallographically, diopside is a monoclinic mineral. It forms prismatic crystals, often with a square or rectangular
Diopside is an important indicator mineral in metamorphic petrology, providing clues about the temperature and pressure
Varieties of diopside include chrome diopside, which is known for its intense green color due to chromium
