Locality type: Quarry Classification Species: Spodumene Formula: LiAlSi2 O6 Comments: rarely as gemmy kunzite, usually white. The prisms average 1 foot long, 6 inches wide and 3/4 inch thick but can reach up to 3 or 4 feet long and 8 to 9 inches thick. Much of it is altered to an albite/eucryptite parallel intergrowth mixture, to "cymatolite" (a parallel intergrowth mixture or albite and muscovite), to granular microcline, or to massive albite and muscovite - or a progressive combination of these replacements. Habit: subhedral prisms, flattened parallel to a {100}, with dome terminations Colour: white to peach Quality for species: Good crystals or rich for species - important (!)
