use the hand to touch the crystal,Wholesale Earring, natural crystal usually temperature than the artificial crystal to cool more.With an eye to observe, natural crystal usually batting inclusions, this is not man-made crystal.
The Amethyst Huang Shuijing such a monochrome crystal, usually observed its two color, even the most top Amethyst Huang Shuijing also have off color, this method can identify whether to add color.Eye view: natural crystal generally have a flocculent (cotton tuft), namely everybody commonly known as flaw, which is a liquid case and carbon dioxide small cavities, and synthetic crystal would not have such a feature.
Crystal is the fineness hierarchy, crystal price influence of many factors, like the diamond to 4C can decide, so please listen more and more comparisons can really tell.General standard is the crystal of the bigger the better, appear more and better, more delicate colors better, shape more typical.
But the most important is their love, and buy, identifying the authenticity of the method generally are the following: (1) see: natural crystal in the process of formation, often influenced by the environment always contain some impurities, facing the sun, when observed, can see the subtle fine transverse lines or catkin shaped material.
While the fake crystal with crystal, glass or slag smelting, after polishing processing, coloring and imitating, no uniform stripes, catkin shaped material.(2) the tongue licks: even in the hot summer of three dog days of summer, with the tongue licking natural crystal surface, also has the cold and cool feeling.
Fake crystal, no cool feeling.(3) the light of: natural crystal is placed vertically in the sun, no matter from which angle it, can emit beautiful luster.The fake crystal is not.(4): natural crystal hardness hardness, gravel used in jewelry gently tap, can not keep a trail; if a streak, is a fake crystal.
(5) use a polarizer to check: in the polarizer rotates under the 360 degrees have Siming four dark change is a natural crystal, no change is the fake crystal.(5) with two color check: natural purple crystal has two colors, the fake crystal no two color.
(6) use a magnifying glass to check: Ten magnification in transmitted light check, can find the bubble basically can be determined as the fake crystal.(7): limited to hair examination is round crystal ball.
Crystal ball is placed on a strand of hair, human hair through the crystal can see double, for crystal ball.Mainly because the crystal with double refraction.But this cannot bring natural crystal, crystal growing and melting crystallization distinguish.
Can distinguish between glass and other materials.(8) using a thermal conductivity detector: thermal conductivity meter adjustment to the green 4 lattice test stones, natural crystal can rise to yellow 2 lattices, and the fake crystal does not rise, when the area is large when rising to yellow a.
