Kunzite with Microcline

Lithium Aluminum Silicate, LiAl(SiO3)2

Spodumene is an important ore of lithium which occurs in lithium-bearing granite pegmatites. It is typically associated with quartz, albite, beryl, tourmaline and lepidolite.

Kunzite is a transparent lilac-colored variety of spodumene, hiddenite is a transparent green vaiety. Both are used as gemstones.

Potassium Aluminum Silicate, KAlSi3O8

Microcline is a widespread rock-forming potassic feldspar with triclinic crystals. Feldspars are widely distributed in igneous, metamorphic and sedimentary rocks.

An essay on feldspars by Anita W. Collins is available.

Stuart provides the following remarks:

"Previous to discovering Kunzite in Afghanistan there were basically only two places one could find this pink variety of Spodumene; Brazil and California (its type locality). As far as I know matrix crystals were unknown. Only very few fine crystals have come from Afghanistan still attached to their matrix."
