Pink Art Deco Riviere Glass 1920's Necklace

Riviere is a French word for river because the stones are thought to flow around the neck, and are traditionally individually prong set, faceted, and with an open back. An authentic 1920's necklace recently acquired from UK.  Each beautiful prong set stone is just on 1cm across and length of the necklace end to end is a small 37cms to be worn as a choker. However nowadays necks are not necessarily small, so I am including a 20cm extension chain which can be attached and varied in the connection to offer any extra room needed, or for some one who might like to vary the length rather than choker length some times. Condition is excellent, gift boxed by Vintageonline.
