RARE Signed DeRosa Sterling Rhinestone and hotsell Enamel Floral Brooch

Absolutely fabulous DeRosa floral brooch, circa 1943-1948. Sterling gold vermeil wash brooch set with the most gorgeous clear rhinestones and finished with enameling. Signed R DeRosa Sterling on the back as shown.

Measures just under 1 3/4" x 1 3/4"

Clasp works great but the bar is very slightly bent as shown. The stones and enamel are in excellent vintage condition. There is wear/loss to the gold vermeil wash hotsell over the sterling which is visible in the photos.
