Regional guide
Epidote from Prince of Wales Island, Alaska, USA
Prince of Wales Island epidote is one of the great American mineral classics: dark, lustrous, sharply terminated, and unmistakably Alaskan in character. The best-known material comes from Green Monster Mountain, with related skarn occurrences in the Copper Mountain–Jumbo district. Collectors prize these specimens for their stout, blocky monoclinic crystals, deep bottle-green to nearly black color, bright vitreous luster, and the striking contrast of white to clear quartz or, more rarely, calcite.
