Precious gemstones should be considered long-term investments that pay off not in interest and dividends, but in beauty, pleasure, and sentimental value that last a lifetime. With proper and consistent care, your best diamond pendant or favorite ruby ring will sparkle and shine as brilliantly after 30 years as it did the day you first brought it home. Here are some quick tips on how to clean and polish your precious gemstone jewelry the right way. Diamonds Whether mounted in rings, bracelets, or necklaces diamonds must be cleaned regularly to preserve their gleaming appearance. To do this at home, first soak the gems in a solution of warm water and mild detergent, and then scrub lightly with a soft brush. Follow up by drying the stones with a soft cloth to restore their original luster. If you want to go the extra mile, you can bring your diamonds to a trusted jeweler once a year for ultrasonic cleaning and professional inspection of the setting and prongs. Sapphires Sapphires are hard and durable, which means they can stand up to intense cleaning measures. An effective at-home method is to prepare a 50-50 mix of ammonia and water, soak the sapphires for 10-20 minutes, polish with a soft brush, and wipe down with a soft cloth. Just remember to avoid harsh solutions if pearls, opals, or other porous gems are mounted alongside your sapphires. Rubies Rubies are resilient enough to receive the same care recommended for diamonds. Ultrasonic cleaning by a professional or home cleaning with warm, soapy water and a soft brush will revitalize your rubies in no time. By being proactive in the care of your precious gemstones, you can ensure that they last a lifetime—and possibly even become treasured family heirlooms that get passed down from generation to generation.
