Is the gold in Guoguang Gold Store genuine?

Generally speaking, they are all real gold, some are as high as four nines, and the styles are also very nice. However, there are also very few merchants who use the vanity of customers to make inferior products, and some even confuse the fake with the real. In short, customers must keep their eyes open when buying to prevent being fooled. In addition, they must issue invoices and certification certificates to the merchants when purchasing, which is almost impeccable.
