Chrome diopside is one of those rare gemstones whose history has truly just begun. The world first heard about chrome diopside in 1988 when rumors of a stunning green gem emerged out of northern Siberia. Due to restrictions caused by the Cold War, access to the area had been very limited. However, the market began opening up after the Berlin Wall fell in late1989.

Supplies of chrome diopside have remained limited, though. The weather conditions surrounding chrome diopside mines are so extreme – yearly temperatures average around 4° F, and lows get down to -50° F – that mining schedules must be restricted or conditions become too dangerous for the miners.
