We love gem Ammolite, and we were very excited to start offering this beautiful material a few years ago after realizing we had never seen it used in body jewelry. These are Ebony and Pink Ivory plugs with 6mm hardware set gem Ammolite cabochons. For more information about the material (origins, what causes the color), visit the encyclopedia page on our site: Ammolite.
