2.5" Purple Fluorite Crystals with Quartz - Mexico
This specimen features purple fluorite crystals associated with quartz and a small amount of pyrite. This crystal cluster was collected from Mexico and comes with an acrylic display stand.
Fluorite also called fluorspar is the mineral form of calcium fluoride, CaF2. It is a colorful mineral both in visible and ultraviolet light and tends to crystalize in isometric cubes, though octahedral and more complex isometric forms are not uncommon. Some of the most common colors are purple, blue, green and yellow. It is a fairly soft mineral being a 3 on the Mohs scale.
It occurs very widely with over 9,000 significant deposits known worldwide.

Quartz is the name given to silicon dioxide (SiO2) and is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich environments--usually igneous rocks or hydrothermal environments like geothermal waters--at temperatures between 100°C and 450°C, and usually under very high pressure. In either case, crystals will precipitate as temperatures cool, just as ice gradually forms when water freezes. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountain formation: these veins can be hundreds of millions of years old.
