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.
Two: 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 glass products when Aniti microscope is making jewelry pictures, we can see the bubbles in the glass products clearly with a portable microscope, magnified 200 times. So you can tell whether it is a glass product or not.
Three: Spectrometer
At present, there are many spectrometers used for jewelry identification. The Opal3000 Pro jewelry identification spectrometer, which enjoys science and technology again, improves the sample testing method of the original jewelry identification equipment, has an open sample operation platform, can measure various jewelry samples more conveniently and quickly, and is very suitable for laboratory use.
