Diamond, английский
- Брильянт - конфигурация головы и плеч, в которой воротник “разорван”, поэтому конфигурация имеет ромбовидный вид;
- Mineral composed essentially of carbon crystallized at extremely high temperatures and pressures; in nature, diamonds form 150 to 200km (93 to 124 miles) or more below the earth`s surface. diamond is the hardest of all known natural substances (10 on the mohs scale); its refractive index is 2.417, dispersion 0.044, specific gravity 3.52, and its lustre is adamantine. diamond ranges from colourless to yellow, brown, gray, orange, green, blue, white, black, purple, pink and extremely rarely, red. transparent and near-colourless is a desirable colour, diamond is a highly valued gemstone.
- A diamond is a precious gem, comprised of a crystalline form of pure carbon, the hardest naturally occurring substance.
- The hardest known substance composed of carbon crystallized in the isometric system, the more common crystal forms being the octahedron and rhombic dodecahedron. the cube and some com¬plex and combination forms of the isometric system are found, as well as rounded, distorted, twinned, and cryptocrystalline forms. although very hard, diamond has excellent cleavage and breaks readily under a blow, yielding flat surfaces parallel to the octahedral planes. diamonds usually are classified as either "gems" or "industrials" on the basis of color, shape, size, crystal form, and the size and location of inclusions or other imperfections. dia¬monds sometimes also are classified on a geographical basis, such as angolas, brazilians, congos, sierra leones, or west africans. this does not strictly mean that diamonds so classed come from that specific geographical area but that they are similar to stones characteristically produced by mines in that locality. a method for synthesizing diamonds has been developed, and small industrial diamonds have been produced on a commercial scale. these synthetic diamonds are commonly called "manmade" and/or "mm diamonds."

- Самый мелкий шрифт размером 3 пункта.
- (от франц . brillant, букв. - блестящий), бездефектный ювелирный алмаз, особая искусственная огранка которого максимально выявляет его блеск. благодаря высокой дисперсии в отраженном свете бриллиант "играет" всеми цветами радуги. масса бриллианта измеряется в каратах (0,2 г).
- , в полиграфии - типографский шрифт, кегль (размер) которого равен 3 пунктам (ок. 1,13 мм); самый мелкий из шрифтов. почти вышел из употребления.
