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.
