Usually, there is a one-to-one "Jewelry and Jade Appraisal Certificate" for the jewelry purchased, but this does not mean that there is absolutely no problem. Some "authoritative appraisal certificates" can be forged. For example, a fake merchant imitates the website of an authoritative authentication institution and enters his certificate number, so that the fake certificate can also find the authentication information in the "official website" he gave you. In addition, there are some small appraisal institutions that live by selling appraisal certificates. If conditions permit, try to choose an authoritative appraisal institution to help you test.

For example:

Peking University jewellery identification center

China Geo University Jewellery Identification Center

National gold and silver products quality supervision and inspection center

Ministry of Land and Resources Jewelry Jade Jewelry Management Center

National Light Industry Jewelry Jade Jewelry Quality Supervision and Inspection Center

And provincial examination centers in all provinces.

Secondly, we can also look at the color of the necklace. The value of jewelry is reflected in its color. The color difference between true and false jewelry is great. The color of natural jewelry is natural, while most synthetic gems are modified and unnatural. Weight measurement can also distinguish the authenticity of Shangmei Paris necklace. Weight measurement is a method to distinguish the authenticity of the same volume of jewelry by testing the weight. For example, many merchants now use artificial zirconia as gemstones, which are similar to diamonds in appearance and are the most ideal substitutes for diamonds. However, if diamonds with the same volume are weighed at the same time as mosan stone, the diamond is heavier and the mosan stone is lighter.

Of course, the simplest thing is that you take the necklaces to the offline store in Paris, Shangmei, or go to a professional jewelry appraisal expert for direct appraisal, so when you buy them, you must go to a regular place to buy these necklaces, so as to be guaranteed.
