How simple and easy to identify true and false diamonds

Diamond is noble luxurious decorations, jewelry is a jewelry that natural diamonds. Diamond, however, due to the scarce and expensive, especially larger grain of diamond, the average person can't. Then, with cheap gems, synthetic gems glass to replace or even pretend to be the activities of the diamond is secretly or publicly intensified, the fake diamond business is increasingly booming up, however, rare diamonds, make it become the main objects being counterfeited. Now more than 10 kinds of fake goods, counterfeit is 'success' is the synthesis of cubic zirconia, commonly known as 'the Soviet drill' thought is the diamond produced in the former Soviet union is wrong. Cubic zirconia: ( The 'Soviet diamonds') : this is the first by the former Soviet union launched the ideal diamond substitute or pretend to be, is a synthetic compound, no natural mineral. After the advent of cubic zirconia, the other a variety of artificial gem raw materials, are only cheap gems substitute for any other purpose, and no longer to counterfeiting diamond grinding. This is due to the cubic zirconia in such aspects as refractive index, dispersion and natural diamond is very close. But its hardness is low ( 5) 6 - 6 - 6, and the thermal conductivity is far lower than the diamond, it is still available instrument accurately distinguish with the diamond. How simple and easy to identify true and false diamonds? From the point of processing, diamond more processed into 58 facet polyhedron, the surface is very smooth; Reflective image never deformation; Small surface and surface between how straight edge, while xinfengrui, multiple edges should be more strictly to. And synthesis of zirconia, because the price is low, hardness is not as good as diamond, small face less flat, edge smooth, more than some edges are not strictly to point. Use a magnifying glass diamonds inside, most of the diamonds can see the black spots or white rock flowers, synthesis of cubic zirconia is very pure, internal rarely see enclosure. Some jewelry store have a little instrument called 'thermal conductivity meter', use high thermal conductivity of diamond to identify the characteristics of a diamond authenticity. When small thermal conductivity meter on the diamond surface, so real diamonds, 'drops', 'drop', 'drops' a very sweet voice, fake diamonds natural won't call.
