Silver on Copper (Ref: 17.1-624)

Keweenaw Co., Michigan, United States
46mm x 27mm x 16mm
minID: XU3-TE8
A classic USA "halfbreed" cluster of crude crystals with a sizable percentage of Silver. Ex Less Hitchings collection, the main "glob" of Silver is 2.3 CM across and has distinct color, form and relief from the Copper. The specimen was purchased in 1967 and as was typical at that time has only the area locality (Keweenaw Penninsula). Good halfbreeds have always been appreciated as classic for the UP, and are unique in the world. This one is particularly rich and esthetic, weighs 57 grams, quite dense for the miniature size.
