This is a AAA sperrylight on chalcopyrite from Siberia, one of two Russian locations where sperrylight is found. Sperrylight is a rare, vital ore of platinum discovered by Francis Lewis Sperry in 1889 and here it appears with chalcopyrite crystal growth for a mixture of gold and silver tones in a metallic, sculptural piece certain to draw notice among your collection.
