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

With the development of science and technology, the imitation of glass products is the most, and it is often difficult for many old experts to distinguish it with the naked eye. Glass products can be easily distinguished by means of portable microscope.

Third, the spectrometer

At present, there are many spectrometers used for jewelry identification, and the updated Opal3000 Pro jewelry identification spectrometer improves the sample detection method of the original jewelry identification equipment.

Gemstone identification types based on extended data;

1, jade identification

Natural jadeite A, jadeite B treated by artificial glue injection and jadeite C are quite different in value. The market is full of artificially treated inferior jadeite. Use Dow filter to illuminate a green jade. If it turns red, it can be said that this piece of jade is dyed, and it is true if it does not change color.

2. Diamond identification

Diamonds are the hardest natural substances. A diamond can carve any other gem, but no other gem can carve a diamond. The most accurate and reliable way to identify genuine and fake diamonds is to measure the thermal conductivity data with a "thermal conductivity meter", but the "thermal conductivity meter" is expensive.
