A rather spectacular specimen of high grade silver! The piece was sliced out of a vein of about 70% metallic silver associated with cobalt arsenides and some dolomite. There is a little erythrite which allows me to conclude that the arsenides are cobalt based. Polished one side and rough-cut the other. Reminiscent of the best high grade days!
