Agate is primarily formed within volcanic rock that has reached incredibly high temperatures. This fascinating material has been used in necklaces and other assorted forms of jewelry for thousands of years, dating back far before the Ancient Greeks. Phillips Collection’s Agate Sculptures take thin cuts of this classic mineral and affix it to a matte black iron base, allowing the natural colors and band formations to take center stage. A lovely accessory piece to any interior space, each of our Agate Sculptures are one-of-a-kind making each piece a special work of naturally occurring art.
