Generally, regular and large gold shops can trade in old ones for new ones. You can change it just by looking at the style. But it depends on whether your old gold ornaments are pure or not. If they are not pure, you need to make up the difference. Then you only need to pay a part of the handling fee. As far as I know, the "Jin Xin Jewelry Laofengxiang Jewelry Store" in Erqi Square will do. It's very convenient for me to exchange gold in Laofengxiang, Luoyang a while ago.
