Pegmatite and spodumene ...........................................
What is pegmatite
Pegmatite is a common plutonic rock, of variable texture and coarseness, that is composed of interlocking crystals of widely different sizes. The most spectacular pegmatites contain abnormally large crystals mixed with medium and smaller crystals. Crystals up to many meters long have been reported. Some pegmatite may be thousands of meters in length and hundreds of meters thick, some appear as dikes, veins, or sills. Pegmatites may be composed of a variety of minerals. Terms such as spodumene pegmatite, granite pegmatite, gabbro pegmatite, syenite pegmatite.
Pegmatite is granite-like rock that isn’t very useful on its own but houses some very precious minerals and elements such as lithium, spodumene, cesium, rare earth elements, tantalum, niobium, and many gemstones including apatite, aquamarine, emerald, garnet, topaz, tourmaline, zircon, scapolite, beryl, apatite, fluorite and zircon. Gem quality stones and elements such as tungsten, boron, tantalum, columbium, bismuth, tin, uranium, radium, sheet mica, and sulfide minerals are found in pegmatite.

What is spodumene
Spodumene is a pyroxene mineral consisting of lithium aluminium inosilicate ( Chemical formula LiAl(SiO3)2 or LIAlSi2O6 ), it is a source of lithium. It occurs as colorless to yellowish, purplish, or lilac kunzite, yellowish-green or emerald-green hiddenite, prismatic crystals, often of great size. Single crystals of 14.3 m (47 ft) in size are reported.
