This clasp contains a really wonderful piece of glass. There is a textured basket-weave pattern beneath a smooth surface. So you get nice texture without having to worry about it catching on anything. The weaving is very clear and very delicate. The small size of the clasp makes it perfect for a small project involving peridot or other similar colored stone. It would complement without overwhelming. The clasp is 27 mm from ring to ring. The centerpiece is 14 mm. The centerpiece is set in a hand-made sterling silver box clasp.
