Large Vintage Sterling & Topaz Brooch/Pendant

Gorgeous estate sterling silver brooch with three blue faceted teardrop shaped blue topaz stones. Purchased at an estate sale, it was marked “blue topaz”, but I suspect they are glass. This mid century modern design has a curved leaf, 3 stems with the blue stones, and a modern circle at the bottom. 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. The rings are closed ring, not split. It is a large piece, measuring 3” long and is stamped, “sterling” on the back of one of the stems. Fabulous piece!
Includes a free polishing cloth.
I am selling without it polished, but a, more than happy to clean it at the buyers request. Just let me know!
