First of all: keep them clean! Lotions, powders, soaps, and natural skin oils can build up on jewelry, cutting down on the brilliance of the gems. Rings in particular tend to collect dust and soap behind the stone, particularly if you wear them all the time. To clean transparent crystalline gemstones, simply soak them in water with a touch of gentle soap or ammonia. If necessary, use a soft toothbrush to scrub behind the stone. After brushing, simply rinse with lukewarm water and allow them to dry. Grease can be removed from plain karat gold jewelry by dipping it into ordinary rubbing alcohol. Rubbing with a soft chamois cloth is an effective way to keep gold jewelry shining.
Avoid immersing your jewelry in chemicals like chlorine. It’s a good idea to remove jewelry before entering a chlorinated pool or hot tub or putting your hands into water with bleach. Chlorine, especially at high temperatures, can permanently damage or discolor your gold jewelry.
There are many types of small machines on the market that will clean jewelry in a matter of minutes using high-frequency sound. These ultrasonic cleaners can be a convenient way to quickly clean your jewelry at home. However, ultrasonic cleaners can damage some jewelry, particularly pieces set with pearls or colored gemstones.
