Kunzite, variety of spodumene, was named for George F. Kunz who was the first to describe this gem in 1902. Gem kunzite is a rose-violet color with strong pleochroism. It is vital that the rough be cut with the correct crystal orientation or the finished gem could be colorless. Kunzite is subject to fading when exposed to strong light.
