Silicon Carbide is a synthetic material used in armor, semiconductors, electronic devices and as an abrasive. Specimens reflect prismatic colors among black crystals. Silicon Carbide rates 9.5 out of 10 on the Mohs Hardness Scale, one half point below diamond. Each specimen is 2+ inches long and 1.5-2 inches across. Each is one-of-a-kind. Size, shape and color will vary.
