Black faceted crystal clasp

This is the little black dress of clasps. It is a vintage Czechoslovakian black crystal set in a hand made sterling silver box clasp made in Istanbul. There are two styles available. The necklace clasp is one ring and is set the long way. It is 29 mm from ring to ring and 13 mm wide. The second style is what I envisioned as a bracelet clasp. The centerpiece is set horizontally and would look great in the center of your wrist. It has two rings. It is 25 mm from ring to ring and 16 mm high.

Please specify one ring or two rings (bracelet style).
