Kunzite is the pink-to-violet form of Spodumene, a lithium aluminium silicate with a hardness of 6 to 7. Its crystal system is monoclinic. It forms as prismatic crystal with vertical striations. It is found in granitic pegmatites, often in association with Feldspar, Muscovite, Quartz, Lepidolite mica and other pegmatite minerals. It can be faceted into beautiful gems, but cutting is difficult because of the stone’s perfect cleavage.
