1. Don't wear ruby jewelry when exercising or doing heavy work, so as to avoid irreparable damage caused by collision. Even in daily wear, we should pay attention to avoid wear and sudden blows, otherwise it will damage even the most difficult gemstones to wear. 2. When storing rubies, store ruby jewelry in a box or a soft cloth so that it won't come into contact with other jewels. Most precious stones are harder than gold, silver and platinum. If they are not placed separately, they may scratch the surface of other jewelry. 3. When wearing ruby and sapphire jewelry, pay attention to check it once a month. If the inlay is loose, it should be repaired in time. 4. Wearing jewelry after modification and makeup can prevent hair gel or cosmetics from damaging jewelry, thus maintaining its color. Ruby and sapphire lose their luster when they are stained with oil and sweat secreted by the human body. So if you wear it often, clean it once a month. 6. Professional nursing that can't be ignored! Normal wearing and pulling will eventually soften the metal parts such as claws of jewelry. Therefore, it is a good way to go to a jewelry store and ask a professional to check your jewelry once every six months. When necessary, professionals can repair claws, ring handles and buckles of necklaces, and reshape deformed rings.
