Hello, Chow Tai Fook. Chow Tai Fook is the most cost-effective brand of gold trade-in. Chow Tai Fook's trade-in is done by the gram, which is more cost-effective than that of Lao Fengxiang. There are no other charges. For the gold ornaments of Laofengxiang brand, the depreciation fee per gram of 7 yuan must be paid, minus the loss 1%, plus 20% of new gold, so the labor cost rises by 20%, and the price is relatively high. Gold ornaments want to trade in old ones for new ones, and of course, gold ornaments with the same preservation rate in grams are preferred. After all, it only needs to increase the labor cost for design. No matter how beautiful other jewelry is, it is easy to lose money if it is exchanged with real gold.
