Spodumene ( Kunzite var. ) LiAl(SiO3)2 is a pyroxene mineral, lithium aluminium inosilicate. This specimen of the kunzite var. of spodumene displays the usual characteristics, with a very pale pink colouration, striations along it's length, and a pitted surface. The pink colour is the result of traces of manganese, and there is some iridescence at the narrow end of the crystal. Spodumene is a main source of lithium. Unfortunately the origin of the specimen is unknown.
