Vtg Signed DeCurtis Floral Swirl Brooch 1/20 12K GF Crystals 1940s 50s

Vtg Signed DeCurtis Floral Swirl Brooch, stamped 1/20 12K GF Crystals 1940s 50s in very good condition. From the Curtis Jewelry Manufacturing Co in R.I. Gold Fill is likely on Sterling Silver but I have not tested. The gold has worn evenly so the piece has a nice warm silver patina unlike cheaper pieces plaited on base metal. It measures 2" x1.5" has a medium sized rhinestone and 15 smaller ones - no stones are missing. The pin also has a link / bail so it may be worn as a pendant. If bail is not desired, remove as it is not well concealed.
