Vintage item. It's a setting AND a bead! Sometimes called Channel Bead Settings, these plastic metalized settings have recesses on two sides to fit an 18x13mm Oval Stone. Use one side for a traditional look or use both sides to create a custom look. With a hole going lengthwise in the center of this setting, they are ready for stringing on a necklace, as earrings, or whatever design you can imagine.
