Broche populaire art déco argent massif France verre vert et marcassite bijou ancien

Exquisite Vintage/Antique Art Deco Sterling Silver France Green Glass & Marcasite Brooch. Beautiful sterling silver fine metal work set with lovely open back shades of green glass stones in the form of long flowers or leaves and surrounded by marcasites set in base and faux pearl ring around brooch. This is fully marked “Made in France” twice and has French sterling silver hallmarks. It also has a makers mark that I can't make out. The faux pearls are strung on string and were then glued down at some time. Probably not when it was made. They are in fair condition with the most wear on the side of faux pearls that were previously glued down and came loose. They could be glued down again. Uploading pics I saw one tiny marcasite missing. Measures 2 5/8 inches long by 1 1/8 inches wide. Has secure trombone clasp. Absolutely gorgeous!!
