DIAMOND INVESTMENT\n\n\nWorldwide Precious Gem Stone Development. A different Giuen\nmultifarious business activity encouraged to a first class of\nconsistency and precision of the knowledge and care required\n\n\nDiamonds is committed to primordial the finest stones, formally\ngenerating California Wealth Management considered intergity entrusted\nwith the responsibility of general delivering uncut rocks from the\nearth to the final gemstones. A diamond in the rough that has the\npossibility of being good, valuable, or attractive, but needs\nimprovement processes a clear , very hard valuable stone, used in\njewelry and in industry. Once mined and processed the next phase is to\nsort, classify and value the diamonds according to size, shape,\nquality and colour. Using more than 16,000 categories the diamonds are\nsorted and then sold to a small group of the world’s leading diamond\ncutters. A mineral also as gemstone precious by virtue of its\ncomposition, hardness, and rarity, cut and polished for ornamental\nuse, or engraved. Of 120 minerals known to have been used as\ngemstones, only 25 are in common use in jewellery; of these the\ndiamond, emerald, ruby and sapphire are classified as precious, and\nthe topaz, amethyst, opal, aquamarine, etc., as semi-precious. Among\nsynthetic precious stones to have been produced successfully, on a\ncommercial scale, are rubies and sapphires (first produced by the\nFrenchman Verneuil in 1904 and 1909 respectively), emeralds (first\nmade by German scientists c. 1930), and diamonds (first made by G.E.C.\nin U.S.A. in 1955). Diamonds were known before 3000 B.C.; and until\ntheir discovery in Brazil in 1725 India was the principal source of\nsupply. Diamonds are found throughout the world from Russia, Siberia,\nYakutia, Southern Africa, Congo, Portuguese West Africa, Tanganyika,\nGhana, Brazil, and Australia. They may be found as alluvial diamonds,\non or close to the earth’s surface in river beds or dried water-\ncourses, or on the sea bottom or else in ‘pipes’ composed of blue\nground or kimberlite, where the original matrix has penetrated the\nearth’s crust. In the latter case the blue ground is extracted, then\nwashed until completely disintegrated, and the residue made to flow\nover vibrating, sloping tables where layer of petroleum grease arrests\nthe diamonds. This involves wastage and x-ray sorting is being\ndeveloped. The blue ground is first crushed and washed until\ncompletely disintegrated, and the resultant diamond inferous\nconcentrates are then passed over gresae tables. The diamonds adhere\nto the grease and the residue is washed away. Further processed the\nbruting involves grinding away the edges of the stone to provide a\nbasic outline, the stone is then given its facets. For a round\nbrilliant cut diamond there are 58 facets. Diamonds are cut by the use\nof diamond dust. The 2 most frequent forms of cutting gem diamonds\nwere the ‘brilliant’ (for thicker stones) and the ‘rose’ for shallower\nones, but in 1961 Arpad Nagy, a Hungarian merchant, evolved the 1 st\nnew method for 500 years, the ‘princess’. To give full refraction of\nlight the back of the diamond is cut into angled and spaced grooves,\nand surface area becomes the criterion of value. Once cut, the stone\nis then graded for cut, colour, clarity and carat weight by a\ngemmological laboratory. Diamond is properly the hardest natural\nsubstance known (10 on Mohs’ scale). Composed of carbon, it\ncrystallizes in the cubic system, other common crystals being\noctahedra and dodecahedra. The high refractive index of 2·42 and the\nhigh dispersion or ‘fire’ accounts for the display of colours seen in\ncut diamonds. Rough diamonds are dull or greasy before being cut, and\nonly some 20 per cent are suitable as gems. There are 4 chief\nvarieties: Well-crystallized transparent stones, colourless or only\nslightly tinted, valued as gems; bort, poorly crystallized or inferior\ndiamonds; balas, an industrial variety, extremely hard and tough; and\ncarbonado, or industrial diamond, also called black diamond or carbon,\nwhich is opaque, black or grey, and very though. Famous rough diamonds\ninclude the Cullian (3,025¾ carats, S.Africa 1905); Excelsior (995·2\ncarats, S. Africa 1893) and President Vargas (726·6 carats, Brazil\n1938).Emerald a presious stone, a bright, grass-green variety of\nberyl. It is transparent or translucent, and the finest come from\nMuzo, in Columbia. Beryl species of presious stone; silicate of\nberyllium and aluminium. Beryl usually occurs as green hexagonal\ncrystals sometimes of large size, found chiefly in granites and\npegmatites; the dark green crystals are termed emeralds and the light\nblue-green aquamarines. Opal a non-crystalline form of silica,\noccuring in stalactites in volcanic rocks. The common opal is opaque,\nmilk-white, yellow, red, blue or green, and lustrous. The presious\nopal is colourless, having innumerable cracks from which emanate\nbrilliant colours produced from minute crystals of cristobalite. Opals\nare found in Hungary, New South Wales (black opals were 1 st\ndiscovered here in 1905) and Mexico, noted for fire opals. Pearls are\ncalcareous substances secreted by many molluscs, which when deposited\nin thin layers on the inside of the shell forms the pearls. Although\ncommercially valuable pearls are obtained from freshwater mussels,\netc., the precious pearls comes from the various species of\nMargaritifera in the family Aviculidae, found in tropical waters off\nNorth and West Australia, the Californian coast, and in the Indian\nOcean. The introduction on commercial scale by the Japanese c. 1920 of\ncultured pearls, produced by interesting an artificial irritant in the\nbody of the oyster, largely affected the value of natural pearls.\nWorld’s most beautiful pearls comes from Japan. Pearls are technically\nnot Gemstones, though the term is sometimes extended to cover them.
