Generous blue and white clasp

This centerpiece reminds me of a pitcher in my Grandmother's china closet. The color was so deep and smooth that it looked like satin. She had a painting of the pitcher that hung next to the china closet. I loved to look from one to the other during fabulous meals. This piece of vintage Czech glass reminds me of that pitcher. The blue shades up to a bright white point. The whole piece of glass, although opaque, is faceted. The centerpiece is set in a hand-made sterling silver box clasp. The centerpiece is 28 mm in diameter. The clasp is 40 mm from ring to ring. Available with one ring or three rings, please specify.
