What a sweet antique sterling silver broach! This dates to the Arts and Crafts Period. It is made of sterling silver and a bezel set piece of abalone. The colors in the stone are very vibrant and change as the pieces moves around in the light. The back is marked Sterling in all capital letters. It has the original clasp and has not been polished in any way. The pin measures slightly under 1 inch long and 3/4 of an inch wide. The oval setting has cutouts and complements the centerstone very well. It is a simple piece that can be worn with other like items or changed into a dependent.
