Variscite
Variscite, with its brilliant emerald green, is an American icon amongst mineral collectors, and the most prized specimens in the world are found in Utah.
Variscite is an aluminum phosphate, making it a cousin to turquoise. The difference is that variscite lacks copper. It was once used as a cheap turquoise knock off but now it is priced much higher than turquoise. It forms near the surface by phosphoric water percolating through aluminum bearing rocks. When the water has dissolved some of the aluminum, it will deposit variscite in cracks in the rock below the aluminum deposit.
Gem variscite is found at four locations in Utah and each is distinct in appearance. The four locations are Ametrice Hill in Tooele County; Clay Canyon in Juab County; Lucin in Box Elder County; and Snowville in Box Elder County.
Clay Canyon the most famous location in the world. It produced nodules up to three feet in diameter. The colors from this location vary from a limey opaque green to a rich translucent emerald green as clear as glass.
There are a number of rare minerals associated with variscite. At Clay Canyon the variscite was found with crandallite, millisite & wardite, gordonite, millisite, montgomeryite, and englishite as well as others.
All the locations for variscite in Utah are now closed so specimens and rough are not being produced any longer.
