The surface of K gold ring may be oxidized with some substances in the air or chemicals in life, and it looks as if it has faded. For example, K platinum itself is slightly bluish white, and rhodium is usually plated on the surface, which makes it look whiter and brighter. But when the coating is oxidized and peeled off, its internal color will be exposed and it looks yellow.

2. The coating falls off:

K gold is made by melting gold and other metals. Some metals are unstable and easy to be oxidized and corroded, so a coating will be added to the surface of jewelry to protect jewelry and delay the oxidation of jewelry. In the process of wearing, the surface of the ring will be worn and scratched, which will cause the coating to fall off, revealing the color inside the ring, and the internal substances will also be oxidized and discolored.

3. Timely remedy:

18K platinum ring is not worn, so it is recommended to store it separately to avoid scratching and peeling of the ring surface coating. When doing housework, it is best to take off the ring to avoid contact with grease and dirt, so as to avoid grease adhering to the surface of the ring and causing yellowing. 18K platinum ring is regularly cleaned and maintained professionally. If it is sent to the jewelry store where the ring is purchased once every six months, you can enjoy the after-sales cleaning and maintenance service.
