Vintage Sterling flower brooch w/open back prong set 4 blue rhinestones -2 1/2”

Pretty vintage Sterling brooch is shaped like a flower with leaves & stem. There are four deep blue prong set rhinestones in an open back. Sturdy clasp. Soft gold vermeil patina. Some tarnish & light scratches consistent with age. The brooch has been in my collection about 25 years. 2 1/2” x 1 3/4”. Good vintage condition. Look carefully at the photos as I try to show all sides of the piece. Bag 3
