Subtle-yet-colorful earrings each feature a moonstone, which is a hand-set glass that is handcrafted in Germany with an opal layer giving it rich luminosity. Because of its handcrafted nature, each stone will be unique. 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.
