If you want to see styles, I think you can look at brands such as Chow Tai Fook, Zhou Shengsheng, Xie Ruilin and Chaohongji. That is, the price is relatively high. Chow Tai Fook, for example, sells by the piece, selling craftsmanship, which is twice as expensive as Yike's old shop. As a famous store, word of mouth is ok. The landlord can buy with confidence. Personally, I think there are still many styles in Zhou Shengsheng, so you can choose rings carefully.
Sorry, I haven't heard of Chengdu Love Jewelry. When buying gold, if you confirm that the store is a regular store, you can generally buy it with confidence. Be sure to take the invoice when you buy it, and see clearly that he wrote all gold/thousands of gold on the invoice to avoid problems that are difficult to solve.
