WebDiamonds were formed over 3 billion years ago deep within the Earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming … Diamond is the allotrope of carbon in which the carbon atoms are arranged in the specific type of cubic lattice called diamond cubic. It is a crystal that is transparent to opaque and which is generally isotropic (no or very weak birefringence). Diamond is the hardest naturally occurring material known. Yet, due to … See more Known to the ancient Greeks as ἀδάμας (adámas, 'proper, unalterable, unbreakable') and sometimes called adamant, diamond is the hardest known naturally occurring material, and serves as the definition of 10 … See more Color and its causes Diamonds occur in various colors: black, brown, yellow, gray, white, blue, orange, purple to pink and … See more Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. … See more • Chemical vapor deposition of diamond • Crystallographic defects in diamond • Nitrogen-vacancy center See more Unlike hardness, which denotes only resistance to scratching, diamond's toughness or tenacity is only fair to good. Toughness relates to the ability to resist breakage from falls or impacts. Because of diamond's perfect and easy cleavage, it is vulnerable to … See more Diamond is a good electrical insulator, having a resistivity of 100 GΩ⋅m to 1 EΩ⋅m (1.0×10 – 1.0×10 Ω⋅m), and is famous for its wide bandgap of 5.47 eV. High carrier mobilities and high electric breakdown field at room temperature are also important … See more Being a form of carbon, diamond oxidizes in air if heated over 700 °C. In absence of oxygen, e.g. in a flow of high-purity argon gas, diamond can be … See more
