Brand jewelry is guaranteed. Cartier, a big brand, is very good, but it is too expensive, and it may be difficult for ordinary people to buy it. Jaff Jefferies in China is quite good recently. Many people won prizes in the Weibo. If you also use Weibo, you might as well go to the lucky draw. Weibo, the official who pays attention to Jaff Jefferies, will have a chance to get the ring by attending the event as required. Other brands such as Chow Tai Fook and Zhou Shengsheng can do it. But I prefer JAFF· jeffries. For reference only.
