Diamonds are symmetrical crystal lines, symmetrical with 3l44l36l29pc, with a strong ethos. The carbon atom is located at the centre of the eight-pointed and six-faced poles that divide the cube into eight small cubes, each of which is occupied by a carbon atom. Each carbon atom is surrounded by four carbon atoms, forming a quadrilateral formulation. The overall structure of diamonds can be considered a combination of quadrilaterals connected to the corner, with co-priced inter-carbon atoms with an atomic distance of 0. 154 nm。

As diamond orientation (111) is the most dense network, diamond crystals are more likely to grow to form the crystal in this direction, thus forming an octahedial crystal。

The second is direction (110) and (100), which can form, respectively, a polygonal polygon of the diamond formation and a cube. Octahedron crystals are the most common, and the probability of retention of the diamond dodecahedron and cubes is reduced in turn。

Diamonds are penetrating。
In addition to this, diamonds can be found in triangles of three or eight hexadecahedrons, four or eight hexadecahedrons, and six or eight hexadecahedrons, which are rare。
The diamond crystals produced by nature are rarely perfect ideal crystals, which, because of their erosion during growth, tend to produce deformations, such as crystal bending, crystal elasticity, and crystal growth often deviates from symmetrical shapes to form crooked crystals。

Diamond crystals appear to differ slightly from one place to another。
Diamonds from the south african mines are visible in various crystals. Brazilian diamonds are dominated by the shoals, followed by polygons, octones and irregulars, in addition to a small number of triangulates. The bulk of zimbabwean diamonds are rounded octopus and cubes. The main pattern of the diamonds in hunan, china, is the arctic shoal, octopus and irregularity。
Synthetic diamonds are completely different from natural diamond crystals. Cvd crystals are plated, and hpht crystals are polygonal and cubic。

So, through crystallines, we can accurately judge whether diamonds are synthesized, can effectively distinguish between diamonds and their imitations, and can provide some basis for the identification of origin。
