Superb, and labor intense design with deep purple / violet coloring. All elements were individually hand applied. The single, large cushion cut center stone is set with dozens of fine prongs. Rhinestones are set at multi levels, very three dimensional. Many chatons surround the calibre cut demi lune shapes. The back displays the intricate craftsmanship of the metal work. Truly a wonderful piece that does not disappoint. This brooch measures 2 inches in diameter and is substantial in appearance, as well a weight. Tube hinge and c clasp. Brass shows age appropriate patina. NO verdigris. Ca., late 1800's, is in very good condition and wears fabulously.
