Lab-created diamond
| Diamond Glossary (алмазы и бриллианты - глоссарий терминологии) |
Lab-created diamonds (also known as man-made diamonds, lab-grown diamonds, synthetic diamonds, and/or cultured diamonds) are grown in highly-controlled laboratory conditions that simulate the earth’s natural growing environment, producing real diamonds that are optically, physically and chemically identical to earth mined diamonds.

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."

Diamond bit, английский
- Any bit having diamonds inset in its crown, which serve as the cutting points or media. commonly also called boart bit, boart-set bit, bort bit, bort-set bit, bortz bit, bortz-set bit.
- A drill bit that has small industrial diamonds embedded in its cutting surface. cutting is performed by the rotation of the very hard diamonds over the rock surface.

Diamond broker, английский
A person who buys packets of diamonds from the marketing agency of the diamond syndicate or other source, re-sorts the diamonds, and acts as a retail agent selling directly to consumers. compare diamond buyer, diamond dealer. 32 a glossary of the diamond-drilling industry

Diamond cleavage, английский
The plane along which a diamond crystal can be split easily. the four planes parallel¬ing the faces of an octahedron are those generally referred to as the cleavage planes, or diamond cleav¬age. all crystalline diamonds are more or less brittle and will be fractured by a sufficiently violent blow, but the irregular surface of a fracture cannot be mistaken for the brilliant flat surface produced by cleaving. the carbon has no cleavage, and in ballas cleavage is absent or very poorly defined. diamond cleaving. the act or process of splitting dia¬monds into smaller pieces, which may be more readily used as tool points, gems, or drill diamonds. diamond concentration. the ratio of the area of a single-layer bit face covered by the inset diamonds or, in an impregnated bit, the bulk proportion of the crown occupied by diamonds.
