Lying is impossible. I bought it there when I got married. I just need to collect their certificate invoices, collect them in five years, and then buy a big one! I don't think this kind of problem needs Baidu, and you can't see your peers defaming you! No matter what brand! The purity of jewelry and gold is the same, and diamonds can't come from the moon. All the same! It depends on who has good service and good after-sales service!
