Chrome diopside is a rich, emerald green variety of the mineral diopside which derives its color from chromium. A recent Russian find in 1988 is the source of the Tsavorite-like stones that are gaining in popularity today.

.

Gemstone quality diopside is found in two forms: the black star diopside and the chrome diopside (which includes chromium giving it a rich green colour). At 5.5–6.5 on the Mohs scale, chrome diopside is relatively soft to scratch. Mohs scale of hardness does not measure tensile strength or resistance to fracture.
