This is a very nice rose cut diamond brooch. The diamonds are set in silver, closed backed, and the piece has been backed in gold. There is a larger diamond in the center, surrounded by 25 other diamonds, if I counted correctly. The back still retains the original "t" hinge and "c" clasp. It measures 1 and 3/4 inches North to South, and 1 and 1/4 inch East to West. This piece is circa 1890, and would be beautiful at the throat of a dress, on a blazer, or on a velvet ribbon, worn around the neck.
