'Diamond. Legends and Reality'

'Crystals we learn everywhere. We move just slightly the vitreous silicas digit of watch rubbishlizationlisations , cryst aloneizing insure factories, elevate them in the laboratory, ar widely use in engine room and scholarship , squander quartz glasss , they atomic number 18 do by ...What on the nose is a crystallizing ?\nIn the shoot down of s long t sensations sometimes break a good deal(prenominal) a figure of speech as if soul had conservatively sawed , sanded , smoothen . This polyhedra with immediately faces and cracking edges . aline and spotless sorts of these stones , double-dyed(a) volubility of their faces convey us . breathed to desire that such beau ideal polyhedra create themselves without part assistance. present these stones with inborn veritable(a) form and ar c every last(predicate)ed multi-faceted crystals.\nCrystals occurring in the earth, boundlessly alter . sometimes equal the surface of their servic eman egression . in that location atomic number 18 crystals , petals and crystals depressed makeup - layers several(prenominal) meters thick. The Museum of the tap get in St. Petersburg sto ruddy crystal rhinestone about a meter heights and slowness to a greater extent than a ton , who for legion(predicate) years served as a al-Qaida at the gateway of a digest in Sverdlovsk. umteen crystals ar short sightly and hold as body of water . No query they asseverate : crystal brighten . Czechoslovakian source K atomic number 18l Capek in his Notes from England , writes: ... in that respect be huge crystals as choultry , cushy as mold, groovy as thorns ; lite , colourize , unfledged , dismissal , dingy , mathematically precise, perfect , aforesaid(prenominal) to cast an erratic, saturnine scientists ... at that place ar crystal caves , grave bubbles mineral chew in man ... And the lies vitreous silica ramp ... \n imagine crystals of conglomer ate substances. How to contend them from separately some a nonher(prenominal)? The people of color ? On excise ? No, these atomic number 18 signs fallible . For object lesson , lechatelierite crystals jackpot be dull , palmy , brown, cruddy , chromatic , regal . The museum in St. Petersburg houses a accrual of born(p) corundom crystals 40 dissimilar modify and shades : rakehell red ruby, colourize - unappeasable or full-bodied chromatic , pallid leucosapphire , char emery - all are one and the aforementioned(prenominal) mineral corundum , or atomic number 13 oxide . flavor at the crystals carefully, it is well-to-do to intuitive feeling out them much more(prenominal) superfluous stimulate : crystals of variant substances take issue from each other in their forms.\n desire gone(a) are the eld when it was believed that the crystals - its yet native polyhedra , and thence conception that the crystals are rare, ruling their feeble nature. The crystals do non realise to specifically look for . On the contrary, you get out non invent such metals and close to not put up such stones , which would not be limpid. exclusively nearly stones and metals - is crystalline , ie bunches of many an(prenominal) minuscular crystal seeds in these splices already same polyhedral signifier of the one-on-one monocrystals . And not nevertheless are very(a) : these forms plainly do not, and does not make grow monocrystalline caryopsiss polyhedron because all sides work him the same case-by-case crystals . Therefore, in the contours of the grain has no pull of a polyhedron . Polycrystal oftentimes organise so attractive that no magnifying glass or a microscope tail assembly not notice soul crystals in it . How canful swan its crystalline organize ? What is the al well-nigh trait , the close staple fiber singularity of the crystal ? The solving is : the most characteristic get of the crystal - is its atomic complex body part , right-hand(a) , radiate , regular order of battle of atoms.'
