This 18-karat yellow gold component mounting features a smooth pearl cup & peg mounting; the cup includes an attach ring. Attach an ear wire for an earring drop, or add a bail and string it onto a chain, cord or strung necklace for a charm or pendant. The cap holds a 6mm (min.) half-drilled pearl or gemstone bead. Use jeweler’s epoxy to secure the bead or pearl on the peg.
