Gem, Rock, and Mineral Postage Stamps Featuring
Diamond


Mineral Name: Diamond

Composition: Carbon

Nomenclature: Named after the Greek word adamas which means "invincible" because of its hardness.

Industrial Uses: Abrasives, precious gemstones.

Additional Notes: Pure carbon forms one of the softest minerals (graphite) and the hardest natural substance (diamond). Despite diamond's unequalled hardness (resistance to scratching) diamond cleaves (breaks along flat planes) easily when struck sharply. When placed in a flame, diamond will burn completely without leaving an ash. Diamonds stick to grease and cannot be wet with water--a property which is used to separate diamonds from crushed rock and dirt. Industrial diamonds, which are used for abrasives, are sometimes referred to as bort or carbonado.
