Large Vintage retail Sterling Silver Brooch

Product Name: Large Vintage retail Sterling Silver Brooch
Gorgeous sterling retail silver brooch with three blue faceted teardrop shaped gemstones. Purchased at an estate sale, this mid century modern design has a curved leaf, 3 stems with blue stones, and a modern circle at the bottom. Not sure what the stones are made of, but they are blue topaz in color. Gorgeous shape and color. It could also be worn as a pendant by slipping a chain through the 2 rings attached to the larger circle. They rings are fixed, not loose. It is larger, measuring 3” long and is stamped, “sterling” on the back of one of the stems. Fabulous piece.
