Learn to see the jade certificate
In fact, one of the most effective ways to identify the authenticity is to have the sales vendor issue a certificate of accreditation from the state. The accreditation certificate of the national authority is quite accurate for the jade identification. It should be said that there are very few “missing goodsâ€, even if there is a problem, the compensation can be pursued.
The "technical content" required here is -- how do you understand the various results of the certificate?
The jade certificate issued by the national authority is one of the results of the appraisal. If it is a natural A-car jade, the result is only the word "Jade", and the words "A goods" and "natural" are not marked.
If it is a B-car jade, the certificate will be marked with the words "Jade (Processing)", "Jade (Glue)", "Jade (B)" or "Jade (Optimized)";
C goods jade, will be marked "Jade (dye)";
D goods jade, in the results of the certificate, there will be no "Jade", what is the substitute, the name of the substitute - such as "artificial glass", "dyed quartzite", "岫Jade, "Malay jade" and so on.
Certificates should correspond one-to-one, that is, one certificate per piece, and the certificate should have the picture and weight of the item.
Although some things come from a piece of raw material, the appearance looks very similar, but the jade jewelry is not exactly the same. One thing has been certified, and it can't prove the quality of the whole batch of things--some merchants have only one certificate for the sample in order to save costs. The goods on the photo are similar to the real ones--this does not determine their The goods sold are all natural, which is not in line with national regulations.
