*** Spodumene Spodumene is a pyroxene mineral that is found, almost exclusively, in granite pegmatites. It has a chemical composition of LiAlSi2O6 but small amounts of sodium sometimes substitute for lithium. Spodumene is typically found in lithium-rich pegmatites in association with other lithium minerals such as lepidolite, eucryptite and petalite. Spodumene often occurs in extremely large crystals.

Spodumene sometimes occurs in transparent crystals in pastel shades of pink, green and yellow. These have been cut into gemstones that are prized by collectors. However, their use in jewelry is limited to pieces that will be subject to limited abuse because of spodumene’s perfect cleavage.
Translucent to transparent spodumene with an attractive pink, yellow or green color is sometimes faceted, cut en cabochon or used to make tumbled stones. Its perfect cleavage limits its use to jewelry that will not be subject to rough wear or handling. Spodumene is primarily a “collector’s gemstone.”
Source localities include Afghanistan, Australia, Brazil, Madagascar, Pakistan, Canada and USA.
Kunzite
Pink to lilac specimens of gem-quality spodumene are highly prized and known as “kunzite”. The color of these specimens is attributed to the presence of manganese as a chromophore. Kunzite is the most commonly encountered spodumene gem.
Hiddenite
Emerald green spodumene is known as “Hiddenite.” Its vivid green color is very similar to emerald and is attributed to the presence of chromium as a chromophore. It is the rarest gem variety of spodumene.
Triphane
Yellow and clear specimens of spodumene are known as “Triphane”. They have also been cut into gems.
