凹熊子AuShongZi電繪材質臨摹-鑽石（金剛石）（Diamond)
鑽石（古希臘文：ἀδάμας；法文、德文：Diamant；英文：Diamond），化學和工業中稱為金剛石。鑽石是碳元素組成的無色晶體，為目前已知的自然存在的最硬物質。
鑽石由於折射率高，在燈光下顯得閃閃生輝，稱作鑽石。巨型的美鑽往往價值連城。當鑽石帶有藍、綠或粉紅色屬十分罕有，而顏色深而鮮豔則價錢更高；目前最昂貴的有色鑽石，要屬帶有濃豔紅色的鑽石。
Diamond (/ˈdaɪ(ə)mənd/) is a solid form of carbon with a diamond cubic crystal structure. At room temperature and pressure it is metastable and graphite is the stable form, but diamond almost never converts to graphite. Diamond is renowned for its superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, it has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial applications of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells.
Because of its extremely rigid lattice, diamond can be contaminated by very few types of impurities, such as boron and nitrogen. Small amounts of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (lattice defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).
