Old piece with silver-washed brass. Much of the finish has long since worn away leaving the brass with a rich, warm, and authentic patina. The base of the stones surely show their age but, wear it well firing off plenty of sparkle. The pin head is 2 inches in diameter. The pin is 11.5 inches overall. Ca., late 19th century and displays beautifully. A charming addition to any collection and does not disappoint!
