Yes, diamonds are one of the purest forms of carbon available, containing more carbon particles than any other allotrope. There are four valence electrons which form the covalent bonds, making a diamond stronger in its appearance and durability. The tetrahedral shape of the diamond that is it has a triangle shape, with six edges, four faces, and four corners.
Diamonds can be produced via manufacturers who use graphite to refine the process and create or grow diamonds in their shops. But, diamonds do occur naturally. By naturally or organically forming, they require four steps to complete the process. These are pressure, carbon, time and heat. By these four working together, a diamond is born.
South Africa is a very famous area for diamond mines, as the diamonds appearance and chemical makeup is considered among the best in the world. These are highly sought after and some have become known as the “blood diamonds,” due to the mining and usage of payments for warlords during conflicts.
