These centerpieces are amazing. The silver foil makes the centerpiece shine. The swirls of light blue and dark blue look like the gamut of sapphire colors, while the silver foil gives the whole think depth. The centerpiece is a vintage German piece made between the World Wars. It is domed and bezel set in a hand-made sterling silver box clasp. The clasp is 28 mm from ring to ring. It is 15 mm wide and 11 mm at the highest point. Available with one ring or two rings, please specify.
