This petite heart pendant necklace features a moonstone, which is a special glass stone crafted in Germany with an opal layer giving it rich luminosity. Because of its handcrafted nature, each stone will be unique. Wear it solo, or as a layering piece with other necklaces. Our silver items have a protective lacquer finish to help prevent oxidation. To care for our silver items, simply wipe down your pieces with a dry, 100% cotton cloth. Keep them away from water, jewelry cleaners, silver cleaners, treated polishing cloths, perfumes, hairspray, lotions, hand-sanitizers and make-up. We offer our own that you can safely use.
