The Carico Lake Turquoise Mine produces beautiful blue Turquoise but is most known for its spectacular shades of lime green colored gemstones. This fabulous lime green coloration is actually caused by a close relative of Turquoise mineral called faustite, the combination of faustite and zinc associated with the Turquoise creates one of the most beautiful coloration effects in American Turquoise that has ever occurred in nature. The Carico Lake Turquoise Mine also produces very rare psuedomorph clams that have been fossilized with Turquoise - this Turquoise is very rare.
