Spodumene is the name of a mineral species that includes two very special gems varieties: kunzite and hiddenite. Spodumene is named from the Greek spodoumenos, meaning "burnt to ash," which alludes to the ashy color of many specimens. A member of the pyroxene group, spodumene belongs to a class of minerals called silicates and it is one of a small number of minerals that contain lithium. Spodumene also occurs in many other shades of colors, all pale but very clear and brilliant. These varieties are given color descriptor names; for example, lemon spodumene.

LWUV: inert yellow, orange, pink to strong orange-red
Color due to iron. Ferric iron produces two lines in the deep blue in almost identical positions. The dominant narrow line at 437nm.is often accompanied by a weaker one at 433nm. the strength of both dependent on the saturation of color. Very little variation in strength is detected with optical orientation

Gentle care. Avoid prolonged exposure to light and heat with kunzite, yellow spodumene and treated hiddenite to prevent color fading. Some stones cleave or fracture easily. Wear with care. Avoid ultrasonic cleaners.
