Compared with traditional gold jewelry, 3D hard gold has the advantages of high hardness, rich modeling and strong texture. Moreover, 3D hard gold can be hollowed out by reverse molding and polishing, which not only saves the amount of gold, but also enriches the styles of products.
As for K gold, it is used to indicate the purity of gold. The higher the purity, the closer to or equal to the spectral color, and the K gold ornaments can be in various colors, such as yellow, white, rose and so on.
However, both 3D hard gold and K gold have certain prices in the market, so if you want to buy a gold bracelet, you need an appraisal certificate. It is best to make sure that there is weight information on the appraisal certificate to ensure that you buy a gold bracelet.
