Discovered in 1902 near San Diego, California. Named after George Frederick Kunz, gemologist to Tiffany & Co.

A variety of spodumene, its delicate violet-pink produced by trace manganese. But prolonged exposure to ultraviolet light causes the colour to fade. The more light it receives, the more it loses.

Found in Afghanistan, Madagascar, and Brazil—Afghanistan's Nuristan province yields particularly large crystals. Barely 120 years since discovery, still new in the world of gemstones. A colour that is not permanent. Handled carefully, for precisely that reason.
