Getting product from rhinestone, carefully study it before purchase. It is often difficult to inexperienced buyer to define fake. Of course, to be fully confident in purchase, crystal needs to be subjected to diagnostics on the gemological equipment. But it is possible to use simple visual methods which will help to define authenticity of subject with high accuracy.
1. In the thickness of rhinestone you will never meet bubbles. Only glass can have such feature. In it gas bubbles of the different size often meet.
2. Investigate subject on availability of svily. So call inclusions which represent the cooled-down lines left the current liquid glass. Often, they are visible with the naked eye. They can be found by consideration of product on gleam. Most often they remind thin threads, tapes and small knots with "tails". Sometimes they are almost not noticeable. To reveal such have twisted, it is necessary to use special ways. For example, to examine subject under beams of the polarized light. Have twisted differ from glass lump on the index of refraction, density and color. In crystal structure of rhinestone of svily cannot be.
3. Before purchase of crystalware carefully examine it. Look for various defects in crystal. It can be cracks and zamutneniye. Their availability demonstrates that this stone is created by the nature, but not the person.
4. Rhinestone, unlike glass, has higher heat conductivity. Apply product to the cheek. The glass subject will heat up at once. Crystal the stone will longer remain cold. Products with low heat conductivity warmer to the touch, than from high.
5. Rhinestone, unlike glass, is not scratched by steel knife. If you have steel knife, try to scratch product a little. Most likely, glass will give in to steel and on its surface there will be scratches. Rhinestone at this procedure will remain in original form.
6. If product thickness identical on all its area, make the next experiment. Look through it at any small subject. Glass has property a little to increase objects. Crystal has no such feature.
7. Rhinestone can visually halve objects. For example, if you put sphere from crystal on the sheet edge of paper, then the edge will look doubled. The glass sphere does not give such effect.
