What kind of gold is it? It's gold plated, placer gold mine, Vietnam. If the introduction is pure gold, ask him if it is 24k, whether it is covered with gold or consistent inside and outside, and whether there is a certificate. Can I claim compensation if it is bought and tested impure? Look at each other's attitude. If it is ambiguous, it means that the ingredients are not pure. If you buy it, you can go to the pawnshop to evaluate it, and someone will identify it. If it is fake, it won't be worth much.
