If you want to buy jewelry, you should pay attention to the quality if you think it is still cheap there.

If it is gold, it depends on whether there are steel seals: gold has AU, thousands of gold, G999 and other steel seals, platinum has PT, and the number behind indicates the gold content, palladium is PD, and 18K gold is G750.

If it is a diamond, pay attention to 4C, the size, color, clarity and cut of the diamond. And the corresponding certificate, at least the national inspection certificate. Also pay attention to the mosaic material. Platinum and 18K gold are better, so it is not safe to consider palladium inlay.

Finally, pay more attention to after-sales service, keep the bills well, ask about replacement and after-sales service, and indicate them on the bills when necessary.

PS: If it's a supermarket brand, it should be carefully considered. Unstable, insufficient after-sales insurance.
