About: Variscite Gemstone
Variscite as crystals is very rare and minute. The massive form or as nodules are fairly common and are used for cabochons and carving. It is a secondary mineral formed by direct deposition from phosphate-bearing water that has reacted with aluminum-rich rocks in a near-surface environment. Variscite is typically opaque, but some stones may be slightly translucent around the edges; and rarely, transparent. The variscite crystal habit is Uncommon as crystals, then pseudo-octahedral may be lathlike; modified by numerous smaller forms, to 1.5 mm. Usually fine-grained massive, in nodules, stalactites, crusts, and veinlets. It occurs as fine-grained masses in nodules, cavity fillings, and crusts. Variscite often contains white veins of the calcium aluminum phosphate mineral crandallite. Variscite is not known to be treated or enhanced in any way. If heated, variscite tends to turn lavender-blue in color, but this is not common. The lime green material from Utah is particularly attractive with its interesting patterns and swirls of bright green colors.
