Metamorphic Rocks and Minerals
Diopside is a calcium magnesium silicate mineral typically found in metamorphosed limestone and skarn environments. It ranges in color from light to deep green and often forms slender prismatic crystals. At Crestmore Quarry in Riverside County, California, diopside occurs in association with a diverse suite of contact metamorphic minerals. Its presence reflects the intense thermal and chemical activity at play in the region and makes it a visually appealing specimen for collectors and geologists alike.
