This is a very unusual vintage Swarovski, because it is not faceted. I took the piece out of the original packaging, so I know it is Swarovski. It has the trademark depth and clarity of a Swarovski, so you can lose yourself in the color. The centerpiece is bezel set in a hand-made sterling silver box clasp. This is a petite clasp that would be suitable for any sort of delicate project. The clasp is 24 mm from ring to ring and 11 mm high.
