At the end of the transaction, the payment was sent to the jewelry counter, and they all accepted the entrustment of the jewelry store. If Tmall sells domestic or foreign gold and only accepts goods from physical stores, why can't it accept online shopping? Maybe you are looking at the same jade, but it may not be of good quality. Gold jewelry can't compare with diamonds, so you can't compare two minerals.
Diamonds depend more on what color you buy, and the quality of different colors varies greatly.
It's simple. Every piece of jewelry of an international brand is designed by a brand spokesperson. Of course, the style is really good. Generally speaking, when you go to the counter to buy gold jewelry, you only need to buy silver jewelry. No one will treat you as a counter, just buy a brand. Is there a problem? Gold jewelry contains precious metals of the same composition, but it is gold-plated. Since you want to buy precious metals, you should follow the rules.
2. Assuming there is no problem when buying, the brand premium is really too high. Personally, I don't think it is a counter. Although it is cheaper, it is not very reliable. I think it's best to have a counter at least when the value of this brand is there.
