The main types of fake jewelry on the market

Since diamonds are noble and luxurious jewellery, it is not uncommon to replace them with cheap gems, artificial gems and even glass on the market. The common types of fake diamonds are as follows:

Zircon

1 Zircon: Very similar to diamonds, it is the best substitute for diamonds. The identification method is that zircon has a polarizing property and a large birefringence. When the processed zircon facet is observed with a magnifying glass of 10 times, it can be seen that the bottom ridge has obvious double when viewed from the top of the face. Shadow, and diamonds have no double shadows.

2 glass: the refractive index of glass is very low, there is no flashing color of the diamond; especially when it sinks into the water, the glass products are all radiant, and immediately reveal the horse's feet.

3 Soviet diamond: namely cubic zirconia, which was first developed by the Soviets, hence the name. The Soviet diamond is an artificial compound, but it is very close to natural diamonds in terms of dispersion and refractive index, and it also has a seductive appearance of "fire". But its hardness is low (8.5), which can be distinguished from diamonds. And the thermal conductivity is much lower than that of diamonds, which can be identified by “thermal conductivity meter” and accurately distinguished.

4 Crystal: Although the crystal is a natural mineral transparent crystal, it is processed like diamond, but lacks the colored light of diamond.

The Anti-Uv Fabric is made of the common fabric after the latest UV-proof finishing. The shielding rate of the finished Anti-uv Fabric is ≥95%, which can effectively prevent the invasion and damage of the UV to the human body, and has the characteristics of non-toxic, non-irritating and washing resistance. The anti-uv fabric is non-toxic, safe to the human body, non-irritating to the skin, no allergic reaction, and has good moisture permeability.
Today's society pays more and more attention to the health of workers. Whether it is anti-static fabric or Flame Retardant Fabric, worker safety has become the core concern of many bosses.
