Diamonds consist entirely of carbon, making them a form of the element in a crystalline structure. Each carbon atom in a diamond is tetrahedrally bonded to four other carbon atoms, resulting in a robust and exceptionally hard material. This unique bonding accounts for the diamond’s prized qualities, including its brilliance, clarity, and durability. While it’s best known as a gemstone for jewelry, particularly engagement rings, diamonds also have industrial applications in cutting, grinding, and drilling due to their hardness. The process of forming diamonds occurs deep within the Earth under extreme pressure and temperature conditions.
