Smooth Onyx Coin Earrings Black : Style 7 of 14 Smooth Black Onyx coins that are approx. 3/4 of an inch across, with a free form smooth Sterling Silver nugget hanging below, surrounded with SS spacer beads. These earrings are a little heavier (and bigger!) than most of my designs, so I decided to make them available only as a post. You can't really feel the weight, because the post keeps them from moving. These look great on, if you are comfortable with a larger earring. Approx. 2 inches long Item: BKE07   $40.00
