The Gemstone Variscite
Variscite is an opaque gemstone with interesting color splotches and veins. It is usually a light or minty-green with whitish patterns. Almost all Variscite gemstones originate from Utah, and for this reason it may also be called Utahlite. In fact, the most important deposit of gemstone-grade Variscite is actually called the Utahlite Deposit.

All About
The unique color habits and patterns of Variscite make it exotic and attractive. However, it is not a common gemstone and thus not readily available. Variscite lacks durability and therefore should not be washed
with chemicals or cleansers. It is also a relatively soft
gemstone, and extra care should be exercised to prevent
scratching.
Uses
?
Variscite is mainly used as a collectors gemstone or exotic green gemstone. It is cut into
cabochons and used as pendants, and is also used in beads and in ornate carvings.
Treatments & Enhancements
?
Variscite gemstones are natural and not enhanced.
Variscite Sources
?
The only significant source of gemstone-grade Variscite is the Utahlite Claim, in the Lucin District, Box Elder County, Utah. Outstanding Variscite
nodules associated with other
phosphate minerals come from Clay Canyon, near Fairfield, Utah County, Utah, and these are sometimes also cut or carved into gemstones.
