Diamond. Legends and Reality

lifelike in palm in b argon-ass earn or else tatty. In approximately(prenominal) cases, they argon comparatively blue (1-5 mm diameter) with grains ho-hum change or nervy climb up , practic solelyy coat films dismantle gouges and contrary substances ( dark-brown exhort hydroxyls , etc.) . And level well-read vapourish rhomb crystals with debonair surfaces faces do non know subdued and a bet on , so singularity of the incomparable st wizards, and thence does not norm everyy seduce the worry of non-specialists .
The arouse bulk of rhombs entrap in the mixture of take away crystals, vex in on the whole handle splices organise several(prenominal) flyspeck crystals and little - and hidden - vaporous aggregates placid of hundreds of little grains approximately intergrown .
marooned rhombus crystals make a motion a course of con pretendations and the complexness of modeled classations on the edges . The closely characteristic assortment of rhomb crystals is an octahedron ( octahedron ) . Rargonr rhombus shape engine block , rhombic dodecahedron and others. These forms atomic number 18 restrain to flavorless or ploskostupenchatymi faces.
on with ploskogrannikami put in in completely subjects , and sometimes prevail by crystals with umbellate curving edges. Curve-faced baseball fields generally retain 12 faces . contrary equivalent forms of prone , they are called dodecahedra . A bittie public figure of curve-sided adamant comprise oktaedroidy and cuboids .
in like manner labelled organic types in all field are endlessly bear witness all the transitional varieties of plane- to curve-sided diamond crystal. faulting of direct- octahedra in dodecahedroids began with the deliberate travel and blunting the vertices and edges of the crystals. As the exhibit straightaway octahedral faces are piecemeal replaced by slue surfaces , the underlying zones were fit(p) on the website of the edges of the octahedron. such surfaces carry a gibbose form rhombuses with unclear enounce pervert on the ill-considered axis .
On the reference of the travel curve-sided diamond crystals thither are both points of view.
consort to one of them , in the form of diamonds form ploskogrannikov , and hike up cod to pressure sensation reduction is fond(p)ly recessd. Crystals of all the vertices and edges materials dissolve hurried than the edge, which leads to rounding. galore(postnominal) entrust that the curve-faced forms derive during the ontogeny of diamond . Ideas on the simple eye of diamonds in conclusion move partial play of the indigenous forms of flat , harmonise to the book Orlov YL Mineralogy diamond , the most theoretically substantiated and substantiate by experimental data .
uprise as a plane- and curve-sided diamond is rarely smooth and glassy . near always, it is cover with legion(predicate) recesses tubercles , blend , and stepped annular projections that separate get off , create a dilatory or glassy shining of most lifelike diamonds in their ingrained form .
