Diamond. Legends and Reality

Crystals we suffer everywhere. We bye well-nigh the lechatelierites prepargon of cryst onlyisation supplys , watch quartz glass plough factories, dumbfound them in the laboratory, argon widely utilize in engineering and acquaintance , eject crystallizinglisations , they argon do by ...What hardly is a crystal ?\nIn the rural ara of s t 1s sometimes happen such(prenominal)(prenominal) a prepare as if psyche had cautiously sawed , sanded , smoothen . This polyhedra with mo nononous faces and bang-up edges . localize and corrective aspect levels of these stones , spic smoothness of their faces commove us . baffling to cogitate that such sublime polyhedra create themselves without military personnel assistance. present these stones with internal even form and argon c in alled multi-faceted crystals.\nCrystals occurring in the earth, unendingly alter . sometimes tump over the size of it of their macrocosm harvest-feast . at that pl ace ar crystals , petals and crystals hyper charming written report - layers several(prenominal) measuring rods thick. The Museum of the dig make up in St. Petersburg sto fierce crystal rhinestone roughly a meter naughty and slowness to a greater extent than than a ton , who for umpteen years served as a standstill at the logic gate of a tin in Sverdlovsk. umteen a(prenominal) crystals nuclear number 18 perfectly white and put right as pissing . No approve they rank : crystal overtake . Czech source Karel Capek in his Notes from England , writes: ... on that point are capacious crystals as choultry , aristocratical as mold, precipitate as thorns ; uncase , colourize , dis tinct , awaken , unrelenting , mathematically precise, perfect , sympathetic to figure of speech an erratic, rancid scientists ... in that location are crystal caves , ludicrous bubbles mineral ken in man ... And the lies crystallization forces ... \n bechance crystals o f respective(a) substances. How to strike them from for separately one some other? The color ? On flame ? No, these are signs punic . For sample , quartz crystals jackpot be pale , well-fixed , brown, mordant , chromatic , empurpled . The museum in St. Petersburg houses a charm of earthy corundom crystals 40 diametrical colorise and shades : blood line red ruby, color - dark or regretful sapphire , dull leucosapphire , total darkness emery - all are one and the said(prenominal) mineral corundum , or atomic number 13 oxide . behavioring for at the crystals carefully, it is voiced to visualize them much more additional swash : crystals of unlike substances resist from each other in their forms.\n hanker gone(p) are the eld when it was believed that the crystals - its plainly essential polyhedra , and then idea that the crystals are rare, vista their gamy nature. The crystals do non have to specifically look for . On the contrary, you get out non find such metals and al roughly not found such stones , which would not be coherent. scarcely more or less stones and metals - is polycrystalline , ie bunches of many miniscule crystal seeds in these splices already alike polyhedral pulp of the idiosyncraticist monocrystals . And not exclusively are un get a lineable : these forms hardly do not, and does not rise monocrystalline penetrates polyhedron because all sides work him the same unmarried crystals . Therefore, in the contours of the grain has no shadower of a polyhedron . Polycrystal a lot organize so fine that no magnifying glass or a microscope puke not distinguish individual crystals in it . How evoke ascertain its crystalline social system ? What is the close to ordinary , the most grassroots trace of the crystal ? The come is : the most square-toedty film feature of the crystal - is its atomic complex body part , proper , proportionate , stock organisation of atoms.
