Under normal circumstances, it is definitely cheaper to buy in a brand-name store than in a domestic store with the same name, but it is definitely much more expensive to buy separately, because diamonds also have international quotations, but if you retail abroad, you can increase profits without discount according to the international quotations. Think about it yourself, and there are few foreign jewels in the shopping mall, most of which are independent stores, and there are some sellers with personal collections, so I suggest. hope this helps
