Recently, Gansu Provincial Market Supervision Administration issued the Report on the Results of Provincial Supervision and Spot Check on the Quality of the Second Batch of Industrial Products in Gansu Province in 20 19. A total of 50 batches of precious metal jewelry and products from 45 distribution enterprises were randomly checked, and 9 batches were unqualified, mainly because the quality deviation and precious metal purity items did not meet the standard requirements. Zhou Dasheng, China Gold, Chinese Jewelry, China Jin Dian and other brands were on the list.

For unqualified production (distribution) enterprises in this supervision and spot check, Gansu Provincial Market Supervision Bureau requires all relevant market supervision departments to deal with unqualified production (distribution) enterprises in a timely manner in strict accordance with relevant laws and regulations, urge enterprises to implement rectification, guide enterprises to strengthen product quality responsibility, strengthen enterprise quality control, and actively assist enterprises to do rectification work. Please ask the relevant municipal (state) market supervision department to report the post-processing situation of unqualified product production (distribution) enterprises to the product quality and safety supervision and management office of the Provincial Bureau on time. Zhou Dasheng said that in addition to establishing a strict internal quality control system, it also ensured that every piece of jewelry sold by brand counters 100% passed the inspection of relevant authoritative national quality inspection institutions.

Compared with gold, the stability of silver jewelry will be worse. As long as the time is long, the silver ornaments will turn black. Nevertheless, the old silverware is still welcomed by people, and its heat is much higher than that of the new silverware. Compared with "new", no matter old gold or old silver, the degree of forgery is more serious. Some merchants even use "old gold and silver with paste, uncertain" as the reason for adulteration of other metals in order to buy suitable ones. Be sure to carefully distinguish between true and false.
