This centerpiece reminds me of a sky at sunset. It is a translucent red/pink background with clouds of AB coating floating across the face. The AB would let the clasp be used with crystal -- it would pick up the crystal color and provide a lovely accent with its red brilliance. The centerpiece is a vintage piece of West German glass. The centerpiece is set in a hand-made sterling silver box clasp. The clasp is 38 mm from ring to ring.
