A superb, incredibly well-crystallized and very aesthetic silver-copper half-breed from the famous Copper Country of Michigan. This beautiful, arborescent specimen is a super combination of fan-like, silver crystals, flattened copper crystals and a delicate latticework of copper microcrystals. Both the silver and copper have a nice patina and a bit of green epidote is a nice compliment. Ex. John Ydren Collection, who according to his card purchased this exquisite old-timer from dealer Brad van Scriver in 1964.
