To maintain the shine and brilliance of your 925 silver moissanite earrings, gently clean them with a soft, lint-free cloth after each wear. Avoid exposure to harsh chemicals, perfumes, and moisture to prevent tarnishing. Store the earrings in a dry, airtight jewelry box or pouch when not in use. For deeper cleaning, use a mild soap solution and a soft brush, then thoroughly dry with a clean cloth.
