This late Art Deco necklace was part of the first jewellery line introduced by Rice-Weiner & Company in 1938. It came in different variations and colours, such as yellow and blue. There were also bracelets and brooches in this series.

This same necklace, with red rhinestones, is shown on page 113 of my book, and also the subject of a blog post you might like: "A Rice-Weiner necklace and my shocking discovery from the maker of McClelland Barclay jewellery".
