These 3200G 1/2 matte rivoli sew-on stones offer up a whole new way to shine. These sew-on crystals look like the popular rivoli component on the top, but are flat and foiled on the back. The facets of this crystal alternate from a sparkling finish to a muted matte finish for a pin-wheel effect everyone will love. The two open holes located on either end of the crystal make this piece easy to sew on to projects.
