Jiangsu Provincial Bureau of Quality and Technical Supervision conducted spot checks on jadeite jewelry products, focusing on the core quality indicators of jadeite jewelry names. In this spot check, all the goods in retail stores and online shopping such as large shopping malls and jewelry shopping malls are qualified, and all kinds of counterfeit and shoddy phenomena are common, which are suitable for tourist attractions. In the commercial area of Sun Yat-sen Mausoleum Scenic Area, the inspectors did not find that the price of jadeite products did not match the real thing. There are many fake jade articles in the scenic spot of Confucius Temple.

There are two kinds of unqualified jadeite products, one is B goods and C goods as A goods, and the other is jadeite made of dyed quartzite and glass. Huang, deputy director of the National Gold and Silver Products Quality Supervision and Inspection Center (Nanjing) and a national registered jewelry inspector, said that this situation is mainly concentrated in the Confucius Temple. All kinds of low-end jewelry display counters are mainly for foreign customers, so shopkeepers sell inferior jade products at will. The so-called jadeite products with a few hundred yuan, the real physical value is only tens of yuan.

Wear c emeralds for a long time.

It will do harm to the body.

Jade is a natural jade, which has not been artificially optimized, and has maintained the true essence of jade quality from the original stone to the finished product.

B refers to the bleached and filled jadeite. Some natural jadeites have impurities. Because the structure is loose after cleaning, they are all cleaned manually with strong acid and injected with resin glue at high pressure. It looks clean and beautiful at first, but it will become ugly after wearing it for a while.

C goods, because some jade itself has no color, but is artificially dyed by laser, usually dyed green and purple. Due to the mixing of industrial pigments, long-term wear will also cause harm to the body. The value of natural green jade seems to be only 1% to 1% of a commodity.

Using dyed quartzite to make jadeite is to artificially dye colorless and transparent quartzite into green, purple, chestnut, yellow and other colors, which appear in a large number of jade market and stalls, and confuse the public with names such as "Ma Laiyu" and "Han Guoyu". The most common products of this kind are ring faces, followed by jade buckles and necklaces. Other jades are rare. The density of dyed quartzite is slightly lower than that of jadeite, and there is towel gourd pulp structure outside.
