Fluorite Cubes on Matrix Tanzanite pyrite is an abundant sulfide

pyrite is an abundant sulfide mineral that despite some similarities can easily be distinguished from actual gold by its crystal form (typically cuboidal) and being much harder whereas gold is soft and malleable

and when exposed to the elements over a long period of time can change into the closely related malachite

this piece consists of beautifully colored cluster of purple octohedral fluorite on a thick base of candle quartz - so named for the appearance of wax dripping down a candle down the crystal face

Fluorite Cubes on Matrix Tanzanite pyrite is an abundant sulfideFluorite is one of the most variable of all crystalline minerals, occurring in shades of blue, green, purple, red and many other colors corresponding to their physical makeup and conditions when the mineral was formed. The name fluorite comes from its use as a flux, or chemical cleaning agent, in iron smelting and other metallurgy. Pure fluorite is clear, but most specimens have vivid color due to various impurities and are often fluorescent. With a
