Gold earrings are not sold by the gram, but should be all gold earrings or gold earrings sold at a marked price. This kind of monovalent gold earrings are generally fine jewelry with 3d hard gold or 5g gold technology.
Whether it is hardness, modeling style or gloss, it is more exquisite than ordinary 999 gold. Because the price of a bite contains a high processing fee, if it is sold by the gram, and then the processing fee is marked separately, the customer will see at a glance that the processing fee is too expensive, so the merchant will not directly mark the gram, which will make the customer feel that it is not expensive, and in this case, the customer will accept it.
