Superb brooch! Done in both stamped and cast silver tone metal that is highly detailed with applied elements. The purple rhinestones are large and prong set. Sky blue Turquoise cabs are sprinkled throughout the filigree / open worked design. The Key itself measures just shy of 4 inches. There are three swagging chains that have a very festoon effect. Including both brooches and the chains, the overall length of this piece is 9 3/4". High quality and well designed. Absolutely wonderful condition! Ca., 1950.
