Extended data:
The purchase of gold jewelry is as follows:
1. The official tax invoice must be provided, indicating the name, condition and weight of the jewelry for future inquiry.
Most of the jewelry sold in the store comes from Shenzhen and Guangzhou, with novel style and beautiful appearance, but the purity is not necessarily high. There are also jewelry made in Zhejiang, with traditional styles but high gold content.
3. Carefully check whether the jewelry has burrs, whether the chain is straight, and whether the buckles, connectors and ear clips are safe. In order to make the buckles, earrings, ears and other parts of the bracelet stronger, the colors of these parts should be reduced.
4. Jewelry will turn white when worn, because jewelry will react with cosmetics, shampoo, detergent or mousse when in contact with each other, and contact with cosmetics should be reduced when worn. If this happens, you can ask the store to use the invoice to solve the problem. When storing jewelry normally, it is best to pack each piece of jewelry separately with a soft cloth to avoid mutual friction and loss.
