Q8L-7TACopper : Cu

Caledonia Mine, Mass City, Ontonagon Co., Michigan, USA

Dimensions: 2 cm x 1.3 cm x 1 cm

2 x 1.3 x 1 cm. An excellent, well-developed, single, twinned crystal of Copper. The crystal has a fine luster and deep brownish-copper color. It is very unusual to find any copper crystal with this fine and sharp of a crystal habit, let alone in isolation. Ex. Wendell E. Wilson Collection.

XK5-LXXCopper : Cu

Multiple photos available
Caledonia Mine, Mass City, Ontonagon Co., Michigan, USA

Dimensions: 12.8 cm x 9.7 cm x 2.6 cm

12.8 x 9.7 x 2.6 cm. A very sculptural, flattened, cabinet specimen of sharply to crudely crystallized, intergrown, tetrahexahedral copper crystals with excellent, variable coppery patina from recent finds at this Copper Country Mine. This striking, free-form specimen looks like a Picasso-like figurine with outstretched arms. This artistic piece looks great from either side and the patina is actually much brighter, than the photos show. Weighs 210 grams or over 7 ounces.

7R2-44TCopper : Cu

Caledonia Mine, Mass City, Ontonagon Co., Michigan, USA

Dimensions: 13.4 cm x 11.4 cm x 4.2 cm

This large, dramatic and sculptural Michigan copper came out of the Seaman Mineral Museum collection. The photos do not come close to capturing the incredible flashy new-penny brightness of this copper. But you can see how wonderfully sculptural the piece is, a sort of garland, with some matrix. It can be beautifully displayed from the other side as well, with a chunk of matrix at the bottom setting off the copper. 13.4 x 11.4 x 4.2 cm
