The new Luccichio collection by Vintouch Jewelry is at once contemporary and timeless. Handmade in Italy from 24-karat gold vermeil, these earrings are set with shimmering crystals on the posts and have a pair of vibrant yellow citrine gemstones at the base. Wear them easily day or night. Cast from 24-karat gold over Sterling Silver. (2. 5 Micron thickness). To protect gold-plating from natural oxidation, a 0. 10-micron palladium plate is applied before the gold-plating process. Palladium is an anti-oxidizing precious metal. We suggest avoiding contact with soaps, detergents, chlorine, and any other chemical substance that could alter the original characteristics of your jewel. When it is not worn, keep your jewelry piece in its bag in order to protect it from natural oxidation. Only if necessary, use a suede cloth and delicately clean the surface of the jewel. Made in Italy in full compliance with the European Reach/Rohs directives and nickel-free to avoid skin irritations.
