Vintage Art Deco bezel set royal blue moulded glass cabochon riviere necklace, open-backed settings in pretty engraved gold tone, 1920s-30s

Vintage rich blue glass cabochon riviere necklace - Art Deco (1930s) or possibly earlier (Edwardian or 1920s). Lovely sized oval blue poured or moulded glass stones, bezel set in lovely open-backed gold tone settings. The stones have a beautiful Art Deco design of indentations - like melon cut glass beads. The settings are really nice quality, with engraved / repousse patterns on the reverse of each. The necklace fastens with a secure spring ring clasp. The necklace has a choker length at about 15 inches, so please check neck measurements carefully. Please ask if you would like a length of extension chain to be added before shipping. The choker is in very good vintage condition.
