Striking Art Deco fur or dress clip, 4" long and 1 3/4" at the widest point. It has molded leaves and a faceted "emerald green" glass stone. The mesh work is reminiscent of many 1920's and 1930's bracelets.
The reverse has a worn fabric covering the clip mechanism. I do not know if this was original or just added for the comfort of the wearer. It can be removed without harming the clip.
Overall condition is very good with expected signs of wear.
