artificial diamond

acrylic rhinestones is the use of scientific methods of manufacturing diamonds, rather than natural diamonds in geological processes formed. Synthetic diamonds and natural diamonds in chemical composition, crystal structure, optical properties and physical characteristics are no different. Most synthetic diamonds according to the different synthesis techniques can be classified as HPHT (high temperature and pressure) artificial diamond or CVD (chemical vapor precipitation method) diamond two categories. CVD artificial diamond and HPHT diamonds and natural diamonds are almost identical, the difference in the atomic structure level, and only by professional appraisers in gemologist room can be identified.

Although acrylic crystals jewelry in the current market share of the low, but its development trend can not be ignored, but also to identify more and more difficult. GIA has been living in the leading position in this area, providing different identification certificate for synthetic diamonds and natural diamonds, in order to enable consumers to better understand the quality of the diamond, so as to avoid consumers being misled.

How to distinguish carbon Silica and diamonds?  

Silica is a kind of synthesis of carbon acrylic crystals. Quality and genuine artificial diamond are very different. Only experienced gemologists can distinguish between the two, so if you have any questions, please diamond to the independent appraisal room identified eligible.
