Most jewelry, including 22kt gold pieces, can be maintained with a nonabrasive jewelry cleaner. Professional cleanings are recommended as frequently as once a year, depending on how often you wear your jewelry. Ultrasonic cleaning is not safe for most gems, so we advise against this method.
Between wearings, it is recommended that you place your jewelry in its original casing or another suitably lined box or pouch. Take care to protect your jewelry from impact against hard surfaces and to avoid contact with abrasive surfaces. Even a diamond can chip if hit with enough force or at just the right angle. Gemstones can scratch other gemstones and wear away at precious metals, so avoid stacking rings and bracelets that can be vulnerable to abrasion. Extreme temperatures, perfumes, cosmetics, and household chemicals can also damage jewelry.
