Agate is a stone characterized by its unique coloring and layers. It can be found in a variety of stones but most commonly associated with volcanic rocks. This rock has been used for centuries as a form of decoration via pins, brooches, beads and marbles. When cut in half you can see all the different layers associated with the natural stone. These agate bands have been popping up all over the high end design world. If you are looking to score some agate products of your own, some of my favorites are at Majorie Skouras Lighting and Rablabs.
