Requirements it is modern the industries dictate the laws: quartz is necessary in large quantities for production of the equipment and exact mechanisms. Therefore emergence in the market of the fakes synthesized in vitro already ceased to surprise buyers. Meanwhile there are easy ways to distinguish natural quartz from artificial.

Instruction
1. Quartz - one of the most widespread minerals. Its elements contain practically in each terrestrial breed. Minerals of quartz group possess the most various and saturated color row. The low price of quartz, its hardness and resistance to damages made it very popular in the jewelry industry. Besides, it is irreplaceable in production of devices and also the ceramic and glass industries.
2. High demand in quartz made it one of the most often forged stones. In the modern market the percent of artificial quartz reaches 85%. At the same time it often are not of a lower quality than natural minerals. Meanwhile there is a number of ways to distinguish natural quartz from counterfeit. Natural quartz has non-uniform structure with cracks, impregnations, vials of air. It has high hardness therefore it is difficult to scratch it. The majority of quartz versions have ability to shine yellow on the place of blow or nadpit.
3. When carrying out the professional gemological analysis it is possible to distinguish counterfeit quartz on the following signs: - natural quartz is not dissolved in acids and alkalis; - natural quartz can weaken or change color when heating or to become absolutely colourless at long stay in high temperatures. If there was a need to distinguish quartz from glass, it is enough to take of it in hands or to concern language. The crystal lattice of quartz differs in smaller heat conduction therefore it practically does not heat up in a hand and to the touch will be always colder than glass.
