This 14/20 yellow gold-filled post earring is set with a faceted 4mm round white topaz and features an open ring that makes it easy to attach a drop or dangle. The friction post features a groove that helps provide the most secure and comfortable fit; post earrings require an ear nut to keep the post in place. Gold-filled earrings deliver karat gold at a more affordable cost than solid gold, allowing you to design with the touch of precious metal customers look for and to offer your designs at a price customers appreciate.
