This technology is often used in shopping malls to discount sales through lottery.

Your certificate is genuine, and a certificate can only prove that your object is genuine.

But it doesn't prove the quality of your object.

This kind of jade pendant inlaid with silver is mass-produced. There is a saying in the jade industry that good materials are matched with good work. This kind of silver pendant belongs to low-end jade products, and its value is not high. Generally, it is sold in supermarkets by lottery. If you buy more than 200, you will lose money.

Actually, 328 is not expensive.

I don't think you need to worry too much.

Just don't buy this lottery discounted item in the future.

good luck
