Hard gold is better, and the manufacturing process is relatively complicated, so the price is more expensive than soft gold. The fineness of hard gold and soft gold is the same, but the hard gold has been hardened by a special process, and it has become ordinary gold after it meets fire. Because the technology is different, the price will be more expensive.

1. Hard gold actually refers to physical gold, but it is "hard" gold made by a new method. Its texture is harder than ordinary gold. Also known as "hard gold with thousands of feet". "3D hard gold" jewelry is a new product that breaks the traditional process and is mainly produced by electroforming. The gold content of 3D hard pure gold is 99.9%, which is consistent with the purity of ordinary pure gold 999.

2. Soft gold is high-purity gold, and hard gold is synthetic gold mixed with other metals, usually copper. Pure gold is too soft to be inlaid. Gold has a high ionization potential, so it is difficult to lose the outer electrons into positive ions and accept the electrons into anions. Its chemical properties are stable and its affinity with other elements is weak. Therefore, in nature, it mostly exists as a simple substance, that is, natural gold.

gold with different hardness has different uses and places. Pure gold is generally soft, and it is better to make gold bars, gold ingots or pure gold jewelry. K-gold has a high hardness, is used for inlaying more, is more reliable, and can also process jewelry with complex styles. In addition, because K-gold is added with other metals, it can present a variety of different colors, so it has a strong sense of fashion.
