Beautiful large oval sterling and turquoise brooch by Chicago Arts & Crafts silversmith Mary Gage. Composed of six chased sterling lily pads that frame a large oval natural turquoise stone that is held in place by silver loops. There are applied silver beads in various locations. This brooch measures 2 1/2" by 2 1/8" and the turquoise stone measures 1 1/4" by 5/8". It is in fine original condition. The turquoise is free of chips or cracks and has beautiful matrix. The silver has a wonderful,warm vintage patina which I am leaving but could be brightened if preferred. Signed Mary Gage Sterling. An exceptional piece by an important women silversmith from this great period of hand made jewelry.
