If these are jewels, they will not be exchanged. Some merchants will give you a warranty on the basis of the ticket at most. There is basically no communication. If you take them back, they are even less valuable. The price of recycled gold is generally not that high.

I hope it helps you. We are Guangdi Jewelry. You can come to us if you are interested. You can find our official website in Baidu Soso. It's not easy to publish a website here. sorry Thank you.
