Vintage Art Deco machine age chrome, burgundy / brown glass geometric necklace with filigree detail

Delicate vintage Art Deco necklace, which is likely to be a Czech piece, possibly even a Neiger Brothers piece. I have seen other examples in various colours elsewhere attributed to Jakob Bengel, but I suspect this is not a Bengel piece. It also has features similar to pieces from French makers like Louis Rousselet. It has classic Art Deco streamlined lines, with beautiful silver and gold tone metal work detailing. The glass colour is most unusual and attractive - a brownish burgundy. The burgundy stones and beads are made of glass. The necklace is in very good vintage condition. The final picture is another example in a different colour that was attributed to Bengel previously on another Art Deco selling site. I also have a version in green available with matching screw back earrings.
