Platinum is a natural white metal with the property of never changing color, which is loved by young consumers. This has also led many couples to choose platinum diamond rings as their first choice for wedding rings. But during the wearing process, some consumers also find that their platinum diamond rings turn yellow. So, what is the reason for platinum diamond rings turning yellow?

Platinum diamond ring yellowing generally refers to the yellowing of the ring metal, and platinum, as a natural white precious metal, does not react with some common chemicals, resulting in a yellowing of its surface. The yellowing of platinum we see is mainly related to the following reasons:
1. Many people like to place gold jewelry and platinum jewelry together, or wear platinum rings and gold rings on adjacent fingers, as long-term close contact can cause platinum rings to turn yellow. Because gold is relatively soft, if rubbed against each other, it can cause gold to stain on platinum, making platinum jewelry yellow and difficult to remove. Overall, platinum diamond rings should not be worn together with gold jewelry.
2. The yellowing of platinum diamond rings may also be caused by excessive accumulation of dirt on their surface, as frequently worn platinum diamond rings can easily become contaminated with dirt. And these dirt will oxidize and turn yellow over time, making the surface of the diamond ring appear to have a yellow covering.
3. When a platinum diamond ring comes into contact with mercury, it also undergoes chemical changes, causing some white spots to appear on the surface of the platinum. If these white spots are not treated in a timely manner, they will turn yellow over time.

The yellowing of a platinum diamond ring may also be due to the yellowing of the main stone in the ring, mainly because the surface of the diamond may be dirty. Diamonds have oil absorption properties. If a platinum diamond ring accidentally comes into contact with oil stains while doing household chores, it may cause the oil stains to adhere to the surface of the diamond, causing it to lose its luster. The accumulation of oil stains on the surface may also turn yellow, making the diamond appear yellow.
