Description: Diamond and graphite shown side by side, for illustrating carbon. Scale is based on a rough approximation. Diamond Locality: South Africa Size: 1.31 carats: 7 x 6 x 6 mm A truly exquisite, super sharp, octahedral crystal of superior quality for a specimen. It is certainly facetable, too. Graphite Locality: El Cochi, Sonora, Mexico Size: thumbnail, 2.5 x 2.4 x 1.2 cm This is a crudely crystallized graphite, colored battleship gray with a resinous luster. I must admit that it is hard to think of this having the the composition, carbon, as diamond. Anyways, a neat locality piece!
