This designer shaped cabochon of Utah Variscite has slight patterns. Variscite is a hydrated aluminum phosphate mineral. It is a relatively rare phosphate mineral that is formed by phosphate rich water deposits that react with aluminum rich rocks in a near-surface environment. It occurs as fine-grained masses in nodules, cavity fillings, and crusts. Variscite often may contain white veins of the mineral Crandallite (a calcium aluminum phosphate mineral). Variscite is often confused with Turquoise. Variscite is normally a more green color, rather than blue. Turquoise coloring comes from traces of copper; Variscite is colored by traces of chromium. Variscite from Nevada can easily be confused with green turquoise since it has black spider-webbing patterns in the matrix, similar to most green turquoise. Most of the Nevada Variscite recovered in recent decades has come from mines located in Lander County in central Nevada. The most notable Variscite deposits in America are found in Utah and Nevada.
