Pink carved glass dome clasp

Gentle swirls are carved into this carnation-pink glass piece. The color is unusual: it is pink with an over-coat of white with the swirls making the centerpiece remind me of a carnation's ruffled petals. The centerpiece is set in a hand-made sterling silver box clasp. The centerpiece is 18 mm across. The clasp is 30 mm from ring to ring. Two rings.
