Spodumene is a member of the Pyroxene Group of minerals that includes Aegirine, Diopside, Hedenbergite, Hypersthene, Jadeite, Petedunnite and Spodumene. Spodumene is also a member of the Spodumene Family of minerals that include Hiddenite, Kunzite, and Spodumene. It is a beautiful gem that is found as colorless, yellow, pale green, deep green (Hiddenite), pink (Kunzite), blue-green and, rarely, blue. Spodumene is strongly pleochroic, meaning it has a color intensity difference when viewed from different directions. It is a very difficult gem to face because of its strong pleochroism, easy cleavage, and splintery fracture.
There are many localities for fine Spodumene crystals including Nuristan district, Laghman Province, Afghanistan; Minas Gerais, Brazil; Maharitra, Mt. Bity, and Anjanabonoina, Madagascar. In the USA, giant crystals in the Etta mine, near Keystone, Pennington County, South Dakota,; at Hiddenite, Alexander County North Carolina; and from the Pala district, San Diego County, California.
