Diopside is a mineral belonging to the pyroxene group, primarily composed of calcium and magnesium silicate. It typically appears in shades of green, but can also be found in white, gray, or black. Diopside is commonly found in metamorphic rocks and is often associated with other minerals like augite and olivine.
This mineral is valued for its use in jewelry, particularly in the form of gemstones. Chrome diopside, a vibrant green variety, is especially popular due to its striking color. Diopside is also studied in geology for its role in understanding the conditions of rock formation and metamorphism.
