Jewelry identification is the identification of all kinds, purity, synthesis, labor, processing and some origin characteristics of jewelry, jade and organic gemstones. By eliminating fake jewelry and jade, we can accurately identify the authenticity of jewelry and protect the rights and interests of buyers.
Identification instrument
First, a magnifying glass
Zircon is very similar to diamond and is the best substitute for diamond. The identification method is that zircon has polarization and large birefringence. Observing the processed zircon prism surface with a magnifying glass of 10 times, it can be seen that the bottom edge line has obvious ghost, but the diamond has no ghost phenomenon.
Second, the portable microscope
Nowadays, with the development of science and technology, glass products are mostly counterfeit, which is often difficult for many old experts to distinguish with the naked eye. It is easy to distinguish glass products with the help of portable microscope (such as Ainiti, Diguang, etc.). ).
Because there are bubbles in the production process of glass products, we can clearly see the bubbles in the glass when we look at the glass products with a portable microscope and zoom in 200 times. So you can tell whether it is a glass product or not.
