GeoGraphic Gems may look like semi-precious stones, but the "gems" in this jewelry are made from vintage National Geographic magazine pages -- marbleized to create vibrant abstract designs. Each hand-crafted GeoGem is mounted on a high-quality bezel and locked under a solid glass dome, making it water resistant and durable. There are many ways to enjoy GeoGraphic Gems: earrings, pendants, bracelets, barrettes, book marks, keychains & more!
