|Kunzite is the best-known variety of the mineral spodumene. It’s named after gemologist George Frederick Kunz, who was the first to identify it as a unique variety of spodumene around 1902. Kunzite gets its color from trace amounts of manganese. California’s San Diego County is an important source of kunzite. It’s also found in Afghanistan, Brazil, and Madagascar.|
|It is not unusual to find kunzite in large sizes. The Smithsonian Institution houses a faceted heart-shaped kunzite that weighs 880 carats. Kunzite can be irradiated and then heat-treated to enhance its color. Both treated and natural color in kunzite can fade with exposure to heat and bright light.|
Kunzite rates 6.5 to 7.0 on the mohs hardness scale, making it ideal for jewellry.
