Which country is a known commercial source of chrome diopside?

Chrome diopside is primarily sourced from Russia, making it a notable commercial source for the gemstone. The deposits found in Russia, particularly in the Siberian region, are renowned for producing high-quality crystals that exhibit the striking green color characteristic of chrome diopside. This mineral's vibrant hue results from the presence of chromium, which contributes to its appeal in the gemstone market.

While other countries may produce diopside varieties, the scale and quality of chrome diopside from Russia set it apart as the leading source. Brazil, Madagascar, and Australia have their own distinct mineral resources, but they are not recognized as significant producers of chrome diopside compared to Russia.
