Diamond fracture and cleavage
WebSummary Calculations of the cleavage energies of various planes in diamond indicated the presence of cleavages other than those already known. A careful goniometric study of … Cut diamonds that have been enhanced to improve their clarity via glass infilling of fractures or cavities are especially fragile, as the glass will not stand up to ultrasonic cleaning or the rigors of the jeweler's torch. Fracture-filled diamonds may shatter if treated improperly. Pressure resistance See more 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 See more Unlike hardness, which denotes only resistance to scratching, diamond's toughness or tenacity is only fair to good. Toughness relates … See more Color and its causes Diamonds occur in various colors: black, brown, yellow, gray, white, blue, orange, purple to pink and red. Colored diamonds contain crystallographic defects, including substitutional impurities and structural defects, that cause … 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 … 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 on the Mohs scale of mineral hardness. … 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 … 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
