Vintage Lucite Bakelite Era Clear Black Flourish Brooch Pin ETC9465

This is a vintage clear & black lucite cut swirl brooch from the bakelite era. This brooch is 4" long x 1 3/4" wide. The pin back is not very secure. I would suggest replacing it. There is some scratching on one end of the clear portion. There is dirt around the crevices of the black piece. One of the cuts isn't' sanded down very smooth on the smallest clear inner corner. Unsigned.
