Heavy Sterling brooch with amethysts in tulip design with leaves. Marked Sterling Mexico on back. Measures 3 3/4" x 2 1/2". One of same design found in Mexican Silver by Penny C. Morrill and Carole A. Berk page 111. The only difference is that the brooch there is all silver without the amethysts and has 4 tulips instead of three like this one. Construction is identical with all marks being same.This is the only one of my best that I sold, and it was literally taken off my jacket at Wolfe's at the Convention and bought on the spot!
