We love the simple and elegant design of these open hoops and especially the touch of sparkle created by the delicate row of 14, 1mm crystals! Each of the tiny stones is claw set, to allow maximum light reflection and so that you can admire them from the side as well as the front. To secure them there is an 11mm long pin and matching butterfly back. This, and their lightweight construction, makes them a great option for children also.
