Wonderful Antique appx 9 or 10k Gold with Rubies Russian Dancer Brooch. Has Slab Diamond chips at waist. Measures 2 inches long and weighs appx 9.9grams. Lovely dancer. Has curved pin back with trombone clasp. I didn't find a hallmark, but believe it is European. I bought as 9k and my jeweler concurred at 9 or 10k and diamond slabs at waist.
