Joseph Wiesner was known for his high quality stones, particularly clear and blue stones being a favorite. This brooch has both, with a dangling lower part. 2 3/4" tall by 1 1/4" at the widest. Small safety clasp. One blue stone on the top edge of the dangle is lighter and the only one of two not open backed. I assume it was made that way, otherwise in excellent vintage condition. Marked Joseph Wiesner NY. Made in the 1950s. The last photo shows the earrings, made by Trifari, listed separately. I always wore these with this brooch (RH1811).
