Final reduction, no offers please :) 1960’s Vintage Dome Latticework 925 Sterling Silver Ring, Blue, Heavy, Size 6.5 I bought this ring from a vintage boutique in NYC a few decades ago. Still love it just never wear jewelry much anymore. It’s a heavy quality piece weighing approx 7.7g It’s stamped 925 and is a solid piece I’m not sure what the stone is. It could be turquoise or it could be howllite.
