Lovely 14k rose gold blue sapphire Ring. This is a gorgeous vintage Russian piece from the USSR. The ring is stamped 583 and with the Soviet hammer and sickle inside the star symbol. There's also another stamp which looks like a .2KK, but I'm not certain exactly what it says. In excellent vintage condition. Sapphire: 1 Carat (apprx) Hallmarked: 583/Soviet Symbols Size: 7.5 (Sits slightly below on mandrel) Earrings: Sapphire 2 Carat ( approx) Hallmarked: 583/Soviet Symbols
