First of all, we should explain the operation mode of jewelry store to the landlord: generally speaking, gold is placed on the counter from mining to jewelry store. There are several links in the middle: 1: mining area. 2. First, some factories (state-owned and private) smelt gold into gold bars or nuggets. 3. Some jewelry processing companies (some only do wholesale) make jewelry through these gold bars (not necessarily domestic gold bars). 4. Jewelry companies (sales, full-time or part-time) sell gold jewelry.

Some famous brands in Hongkong and Chinese mainland can't 100% produce their own jewelry. So they will also go to the wholesale company to get the goods. General service will require wholesale companies to put their own company logo on the goods they choose. According to the regulations, unsold goods produced by wholesale companies must be stamped with gold purity stamp, such as "thousands of pure gold" and company code stamp, such as "IV".

The landlord's situation may be: 1, the wholesale company missed printing; 2. The company selling jewelry didn't ask anyone to stamp it; The brand that the landlord said is not famous. If the landlord is really worried about the gold content, go to the jewelry testing center for testing. However, the general cost of testing is quite high, because the landlord is only a product, it is hard to say whether anyone is willing to test. In addition, you can go to the stores of well-known jewelry companies to exchange gold, such as Chow Tai Fook, which means there will be a price difference.

Finally, I hope the landlord problem can be solved.
