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!
