Collectors love kunzite for its color range, from delicate pastel pink to intense violetish purple. Kunzite is the best-known variety of the mineral spodumene. It’s named after famed gemologist George Frederick Kunz, who was the first to identify it as a unique variety of spodumene. Kunzite gets its delicate color from trace amounts of manganese. California’s San Diego County is an important source of kunzite.
