Genuine Agate stones provide a twist on traditional Tiffany materials. Each Quoizel Agate Stone shade is made by hand by skilled craftsmen. Each stone is hand-selected for quality and size, cut in half, placed in a tumbler for 72 hours to make them smooth and round, hand-polished and then distinctively placed to achieve the most dramatic effect. And dramatic it is! This piece is sure to be the talk of your home.
