Grace & Wood Co. jewelry is made with genuine Sterling Sliver, 14K Gold Filled, or 14K Rose Gold Filled metals. Our studs use hypoallergenic Titanium posts. Because we use precious metals, you may notice some tarnishing. Using a polishing cloth will quickly bring back the original shine and luster of your jewelry. All our wooden pieces are sealed, but it is best to avoid getting them wet. We recommend hanging your earrings or storing them flat. If anything should go wrong with your jewelry, please don’t hesitate to contact us so we can make it right.
