by LoveRed » May 16, 2018 I have an old large ring gotten from a lady who would go home to Poland and buy Russian jewelry from women trying to get out of Russia. So it is pretty orange but saw orange looking citrine online. The ring has a very substantial setting, fancy gallery and is between 18-20karat . Went to a couple pawn shops hunting and we started talking stones. He had a tester that has a needle that goes higher as the stones move towards diamond. This registered as sapphire surprising us both. Must be synthetic? But awfully nice setting for fake stone. Input appreciated.!!
