An entirely unique accessory, made from naturally formed, hand-polished petrified wood, these stone sets are ideal for adding a touch of flair to a dresser, coffee table or sideboard. Petrified wood is the result of permineralization which turns wood to stone. The process takes place when wood becomes buried under sediment or volcanic ash and is preserved due to a lack of oxygen. As a result, each of these decorative pieces are one-off products and will vary in appearance, some lighter, some darker, as the original wood grain dictates.
