The Fine Jewelry Cleaner is safe to use to clean diamonds, cubic zirconia, moissanite, sapphires, gold, platinum jewelry and more. The cleaner uses an advanced surfactant-based formula rather than a detergent-based one, requiring no agitation or rinsing, leaving jewelry sparkling. Lightly scented and designed to be used daily. Ideal for: Bridal jewelry, engagement rings, and other fine gold and platinum jewelry. Do not use on pearls or other porous gemstones. NOTE: These cleaners remove grime, oil and dirt but will not remove tarnish. Contact Christina to discuss professional steam cleaning, polish and fresh rhodium for your pieces to sparkle like new.
