Designer B.S.K Brooch - Large 3" Vintage Aqua Enamel Flower Pin

B.S.K. was a jewelry company founded in 1948. They made quality jewelry, often using enameling and rhinestones. This piece is a large (about 3") flower pin with aqua enameling on brushed gold tone metal with clear rhinestones in the center. Most likely from the 1950's.
All rhinestones are present. There is some age-appropriate enamel loss. Overall good vintage condition.
From smoke-free household.
