Spodumene

Spodumene is a comparatively rare mineral found almost exclusively in lithium-rich pegmatites. It is worked as an ore of lithium but is it most highly prized as a gem mineral. Discovered in 1800, it was named after the Greek spodumenos reduced to ashes, alluding to the grayish-white mass that is formed when the mineral is ignited.
