A diamond's fracture is irregular. Diamonds which are nearly round, due to the formation of multiple steps on octahedral faces, are commonly coated in a gum-like skin (nyf). The combination of stepped faces, growth defects, and nyf produces a "scaly" or corrugated appearance. Many diamonds are so … 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 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 See more Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200 W/(m·K), which is five times more than silver, … See more Known to the ancient Greeks as ἀδάμας (adámas, 'proper, unalterable, unbreakable') and sometimes called adamant, … 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 be heated up to about 1700 °C. Its surface blackens, but can be recovered by re-polishing. At high pressure (~20 … See more WebWhen diamonds have inclusions, either naturally occurring or made by laser drilling, the result is a fracture filled diamond. Fracture filling diamonds started in the 1980s. When surface-reaching fractures are filled with the glassy resin, they become more difficult to see, improving the apparent clarity grade of a diamond.
