A very showy and large epidote crystal from the famous Green Monster Mountain on Prince of Wales Island, Alaska. This highly lustrous and beautifully striated, dark olive-green crystal is nicely accented by smaller epidotes and needle quartz crystals. This is a large and very highly representative specimen of the species and locality. The termination area is essentially pristine. A couple of broken quartz crystals and the out of sight contacting on the back are certainly not detraction. A major, large epidote from the John Ydren Collection.
