Rainbow purple gold round flower clasp

I struggled with a name for this clasp as I find it eludes description. It is a piece of Czechoslovakian pressed glass with some stylized flowers in the middle and some other designs around the edge. The finish is gold AB with a predominance of purple and fuchsia with some gold-green highlights thrown in for good measure. The clasp is 28 mm from ring to ring. It is 20 mm wide and 12 mm high. The centerpiece is bezel set in a hand-made sterling silver box clasp. Available with one ring or two rings, please specify.
