This vintage BSK brooch looks like curled ribbons forming a flower with a center of rhinestones and faux pearls.
The brooch is 2 3/8" wide and 1/2" deep. The rhinestones are two rich tone of emerald. Around the open-work cage are eight little columns topped with small faux pearls.
The petals themselves have bright-cut accents. The pin has a safety clasp back; BSK is cast on the reverse of the pin. Condition is very fine.
