Our pewter pendants are sculpted to resemble the blemishes and imperfections of stone. The natural process that forms a patina on pewter will occur over time, giving the pendant the intended look of an ancient, weathered Ogham stone. If you prefer to maintain a sheen to your Ogham pewter pendant, please use one of the many simple techniques to polish pewter jewelry such as massaging baking soda onto the moistened pendant and rinsing with warm water.
