I come from Hong Kong. I just went to Lukfook the other day and bought a platinum jewelry. Because the price of precious metals changes every day, they can't mark all the jewelry with price, only with weight. Then calculate the selling price according to the price of the day.

But they usually weigh a pound before you receive the jewelry, and then let you have a look to make sure that the actual weight is the same as that on the label. If it's the same, it means no problem.

And the invoice will also record the trust information of the jewelry you bought. Besides, don't worry, chain gold shops in Hong Kong won't cheat people. If you find them cheating, you can sue them and ask them to pay you a lot of compensation. . .
