Swarovski 3252 Emerald Cut Sew-on Stones take the beauty of the classic emerald gemstone cut and recreates it in the form of a sew-on crystal. This look is traditionally used in jewelry but can now be used in other ways. Emerald Cut Sew-on Stones feature holes that make application easy and can lay flat against fabrics and other wearable items. Shown here in Crystal AB, 28x20mm.
