One of the precautions in buying a gold necklace is to look at the purity: as the saying goes, "gold is not enough", and the common gold on the market is usually called pure gold. Buy gold necklaces through regular channels, and the necklaces are marked with "pure gold" or "999". Please pay attention to them.
The second thing to pay attention to when buying gold necklaces is brand selection: choosing a big brand with good reputation will usually avoid certain risks, and the possibility of shoddy will be relatively low.
The third point to pay attention to when buying a gold necklace is the craftsmanship: this is closely related to personal preferences. If you are young, you don't have to pursue the weight of gold too much. Instead, you can choose a gold necklace with novel style and exquisite craftsmanship, which can better set off the taste of young people. Now there are 3D hard gold on the market, which can increase its hardness without changing the gold content, so that gold can make a fresher style. If you don't cling to gold, fashionable and generous platinum necklaces and K gold are also good choices. If you are an elderly person, it is recommended to choose a gold necklace with decent style and heavy weight, but you don't have to pay too much attention to craftsmanship.
