The hardness of pure platinum is higher than that of pure gold and pure silver, but lower than that of most ionic and atomic crystals. When the surface of platinum jewelry is polished, rhodium plating is generally used to keep it smooth and rust-proof. However, because the hardness of rhodium is not indestructible, polished platinum jewelry is really easy to wear and lose its luster, but the chemical properties of platinum are stable, and even if it is worn, it usually does not rust.
Extended data:
After buying a platinum ring, its maintenance is also more important. You should pay attention to the following points:
1. When not in use, put the platinum ring alone in the jewelry box or soft leather pocket.
2. Don't wear a platinum ring and gold jewelry at the same time, because gold is soft. If they rub against each other, the gold powder will be adsorbed on platinum, which will turn platinum yellow and affect its unique pure luster.
3. If you wear it frequently, clean the platinum ring regularly to keep it shiny. You can use jewelry cleaners sold in the market, or you can clean them yourself. Soak it in a solution of soap and warm water, and then gently wipe it with a soft cloth.
4. If your platinum ring is inlaid with diamonds, don't let the platinum ring you wear get oil or bleach when you do housework. Although chemicals will not damage platinum, they may discolor diamonds or precious stones.
At the same time, I suggest that you send the platinum ring to the jewelry store for inspection every year, and carry out professional cleaning and renovation in time, so that the platinum ring can be worn often, and many businesses provide free cleaning.
