Carbon (from Latincarbo "charcoal") with the chemical symbol C is a chemical element that occurs in nature in its pure form predominantly in two very opposite appearing allotropic modifications, namely as graphite and diamond. A third, but very rarely occurring form of carbon is the mineral lonsdaleite, first described in 1967, which is also called hexagonal diamond because of its hexagonal crystal structure.
