This 14-karat yellow gold ear post features a unique double-ended design. Each end accommodates its own pearl. Secure a half-drilled pearl to the front peg and cup (3.5mm) using jeweler's epoxy. Then widen the hole on a second half-drilled pearl to accommodate the threaded ear nut (.078" dia. x 2mm) and secure it into the cup on the nut (4mm) using jeweler's epoxy. When the nut is threaded onto the post, the earring will have a pearl at each end.
