Diamonds are an allotropic form of carbon
History of Moderator - Lisboa, Portugal
Diamonds are an allotropic form of carbon, with each carbon atom bonded to four others, forming a structure that can only form in the deepest layers of the Earth, due to high pressures and temperatures. These are then expelled into the earth's crust, where synthetic diamonds are also created by modifying the crystalline structure of graphite. The different colors of diamonds can be caused by impurities such as nitrogen for the yellow color or boron for the blue color. Another cause could be deformations of the crystalline lattice, resulting in rare brown, pink or red diamonds... Did you know?
