Synthetic spinel and other similar gem cufflinks difference method as follows

The spinel is a mid-range gem cufflinks, supposedly made by artificial means, the economic interests is not very high. However, due to the easy production, low cost, and dyed the color of all the necessary, it is often widely used as substitutes for precious gemstone cufflinks and even bogus products. The easy way to distinguish synthetic spinel and natural spinel polarizing principle to detect. Synthetic spinel are equiaxed, should be a homogeneous body, but it has a strong abnormal heterogeneous. Usually, the cufflinks will cost a great deal of money, generally a few hundred dollars to the million. Put it in the polarimeter, ruby cufflinks, orthogonal polarization rotation can be seen that the synthetic spinel brightness variations. The brightness changes for the entire gemstone cufflinks are very uneven, irregular bright and dark with white, sometimes into the bright and dark lattice.
Turn the gemstone cufflinks, bright and dark with a wave, step by step towards a direction, which is called "wavy extinction. Natural spinel is generally no exception heterogeneous orthogonal polarization observed in the polarimeter using the rotating gemstone cufflinks, it is always dark. Brightness changes, and very weak, and no wavy extinction phenomenon. Typically, there are top brands of cufflinks like GUCCI, Ver-sace, LV, Cartier, Tiffany, Ste-fano ricci, Dunhill, Montblanc, BOSS, Dolce & Gabbana and others. Often appear in artificial rubies and sapphire cufflinks arc-shaped stripes and ribbons, spherical bubbles, and a plume of clouds shaped inclusions, but in the synthetic spinel are rarely found, but once you see can be identified as man-made products. In natural spinel inclusions are small crystals of the angular mineral.
Blue synthetic spinel, blue in the composition of metallic cobalt dyed. Natural spinel without cobalt, due to their blue line with cheap iron. Therefore, we can use the spectroscopic observation of suspected gem cufflinks, orange to green parts of the spectra show, showing cobalt caused by three wide black belt, it must be man-made products. They would also introduce new styles of cufflinks. The same time, only the naked eye can be seen, man-made sapphire cufflinks spinel glow in the dark blue, red, especially in the more obvious turn the gemstone cufflinks. Natural products for the pure gray and blue, the rotation will not be flushed. Synthetic spinel and other similar gem cufflinks difference method as follows: First synthetic spinel equiaxed, only one refractive index, so it no dichroism. We can, through this two points with a number of two (or three) index of refraction and dichroism of the heterogeneity of the treasure, for example, ruby cufflinks, sapphire cufflinks, such as phase difference.
In the natural spinel, there is no clear, colorless, but it is easier to produce clear, colorless synthetic spinel, synthetic spinel The main purpose is to use a substitute for diamonds or bogus products. Of course it is very easy to distinguish between genuine and fake diamonds. Some even will also introduce cufflinks of limited edition.  The first is the refractive index of diamond refractive index of 2.42, far beyond the measuring range of the light meter rate, and synthetic spinel is only 1.73, used up rate meter can be measured. In addition, gemstone cufflinks carved hardness nine cufflinks standard piece of artificial sapphire, synthetic spinel hardness 8, slipping only in the standard on-chip program does not move, diamonds can easily scratch the synthetic sapphire cufflinks Standard film. Set for a bunch of good diamond necklace or a bracelet.
