To put it simply, they are all the same, there is no difference, because these diamonds and metals are not produced by themselves, they are retailers, not manufacturers, so the quality of products is the same. If we stick to the characteristics, the development of Chow Tai Fook and Lukfook may be more distinctive, that is, there will be more styles and the styles will be updated faster, but some of them will be too advanced to wear! Another feature is that these brands are very expensive! Especially Chow Tai Fook and Luk Fook, which were bought from Mr. Zhou, were discounted, and the blow was still relatively low! Xie Ruilin will also be cheaper! That's all!
