This masterful piece of art is one of the most exquisite brooches I've had the honor to own...an elaborate and classy design set in warm, shiny gold tone metal are oodles of clear, sparking rhinestones in all sorts of shapes and sizes...rounds, baguettes, marquis...it is absolutely stunning and magnificently made. There does appear to be a plaque on the back that housed a signature but it is worn off and even my strongest loupe can't make it out. I'm certain this is an important piece and it will make a significant addition to any vintage jewelry collection. Measure is approx. 3" x 1.5".
