Heyuan Huiyuan jewellery gold shop

Radiation metal should not be a big problem, the key is the weight of the chain, you can simply calculate: weigh the chain, 1g 3.2 yuan, if your silver chain is 3g, then the material cost of this chain is about 10 yuan, and the labor cost and electroplating cost are about 6 yuan, so the retail price of that chain is reasonable. It shouldn't be fake!
