Spodumene
Spodumene is a pyroxene inosilicate mineral. It is noted to occur in two collectible varities, Kunzite (Pink), and Hiddenite (Green). The most common form of Kunzite is crystal fragments chipped off of complete crystals. However, large crystals of Spodumene have occured, with some crystals reaching a length of over 10 feet. The mineral contains lithium, a rare metal used in rechargable phone and car batteries.
Uses
In addition to having collectible varities, Spodumene is a major source of Lithium, a rare alkaline metal used in rechargable batteries for vehicles and consumer electronics.
Notable Localities
The largest crystals of Spodumene are found in several pegmatites nestled in Afghanistan. Fine specimens of Kunzite have also been discovered in the Pala District mines of San Diego as well as the Granite quarries of Newry, Maine. Hiddenite was discovered in a namesake North Carolina Appalachian town.
