| − | '''Diamond''' is an [[allotrope]] of [[carbon]], and is formed when carbon atoms are arranged in a tetrahedral fashion when put under immense amounts of heat and pressure. Diamonds are created in the earths mantle, due to forces and heat required for their creation, and are most often brought near the surface through volcanic eruption. Diamonds are also noted for being the hardest natural material on the [[hardness|Moh's Scale]], and fairly rare (deposits are found in [[Kimberlite]] in [[South Africa]]). As such, natural diamonds are used for jewelry, and synthetic diamonds for drill bits. | + | '''Diamond''' is an [[allotrope]] of [[carbon]], and is formed when carbon atoms are arranged in a tetrahedral fashion when put under immense amounts of heat and pressure.
