1. Don't wear ruby and sapphire jewelry when exercising or doing heavy work, so as to avoid irreparable damage caused by collision.
2. Don't put ruby jewelry and other jewelry in the same drawer or jewelry box at will. Because all kinds of gems and metals have different hardness, they will be worn by mutual friction.
3. When wearing ruby jewelry, pay attention to check it once a month. If the inlay is loose, it should be repaired in time.
Ruby, like other gems, will lose its luster when it is stained with oil and sweat secreted by human body. So if you wear it often, clean it once a month.
5. Especially mention borderless and micro-inlaid jewelry. Be careful in daily wear and try to avoid big collisions. If it is found that the borderless inlaid jewelry falls off, it should be repaired as soon as possible to prevent the gem from falling off in a large area.
6. Acid and alkali substances have corrosive effects on rubies, which make rubies discolored. Therefore, we should try to avoid the corrosion of rubies by acid and alkali substances such as soap, washing powder and detergent.
