Seam rings give the appearance of wearing a closed ring without having a bead or exposed clasp. Made from high-qaulity niobium, these rings can be used in a variety of piercings for a classic look. Our 18ga niobium seam rings are available in three sizes. 1/4", 5/16" and 3/8" inner diameter. NeoMetal niobium seam rings are pre-spanned to assist in a better polish of the cut surface. The rings remain open when shipped to minimize the manipulation of the metal.
