Spodumene - Wikipedia
网页Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate, Li Al (Si O 3) 2, and is a commercially important source of lithium. It occurs as colorless to yellowish, purplish, or lilac kunzite (see below), yellowish-green or emerald-green hiddenite, prismatic crystals, often of great size.
