To maintain the brilliance of your 925 Sterling Silver Moissanite Cuban Chain, avoid contact with harsh chemicals, perfumes, and cosmetics. Gently clean with a soft, dry cloth after each use to remove oils and dust. For deeper cleaning, use a mild soap solution and rinse thoroughly with clean water, then pat dry with a soft cloth. Store your chain in a cool, dry place — ideally in a soft pouch or jewelry box — to prevent scratches and tarnish. With proper care, your chain will maintain its sparkle for years to come.
