1, different purity

The difference between pure gold and k gold mainly lies in purity. The purity of pure gold is about 99%, which can be regarded as pure gold, while K gold is an alloy synthesized by a certain proportion of gold and other precious metals, and its gold content is much lower than that of pure gold.

2. Different hardness

Pure gold has high ductility and easy deformation, and is not suitable for inlaying diamonds, pearls and other ornaments. K gold is an alloy containing a small amount of silver, copper and zinc. Its strength and toughness are greater than pure gold, and it is more suitable for making various ornaments.

Step 3: Different colors

The composition of pure gold is gold, so the color is single gold with high gloss. Alloys have different colors according to their composition, including rose gold, yellow and white. At the same time, the luster is slightly lower than that of pure gold.

K-gold product characteristics

One of the characteristics of gold is its high ductility, so it is difficult to inlay various exquisite styles, especially when inlaying pearls, precious stones and jadeite, it is easy to lose. Therefore, people add a small amount of silver, copper, zinc and other metals to gold to increase its strength and toughness. The gold ornaments made in this way are also called K gold.

K gold can be made into various colors as needed. K-gold jewelry popular in the world has various colors, and the common ones are yellow and white. When 25% palladium or nickel is mixed with gold, it will turn white, and its main component is gold. This is called platinum.
