Flat shell hoops. Each iridescent shell hoop has a natural mother of pearl lustre & has been dyed creating a unique washed effect. The beads have a hidden edge-hole, drilled through the centre, so that the beading wire can be threaded from one edge to the other seamlessly. Tip; the thread will only be visible in the centre of the hoop, where you can choose to add a smaller bead to hang in the middle of the hoop too!
