Let's just say that you can go to the official Tmall stores of major brands. Don't trade in official website casually, because jewelry is a precious commodity and not very safe without the support of third-party supervision and logistics. Taobao Tmall's Alipay should be said to be the most powerful third-party fund supervision in China, so if you must buy jewelry on the jewelry website, first consider the delivery safety.

Besides, official website of many big jewelry brands is not perfect, offline is very strong, online is chaotic, and you may be cheated by those high imitation websites. If you don't have the ability to identify the authenticity of jewelry websites, I think it's best not to sell them online.
