Light blue and silver helix clasp

This centerpiece started life as a shank button, but I thought it was better off as a clasp. The light blue background is slightly textured with a very fine and delicate basket weave. The three swirls are also very delicate, barely more than a whisper of silver However, the silver is raised and etched so it looks like it is set with small stones. I believe the button was made in West Germany after WWII. The centerpiece is bezel set in a hand-made sterling silver box clasp. The clasp is 28 mm from ring to ring, 18 mm wide, and 8 mm high.
