1950s sterling Castlecliff mid century heart brooch. The outer heart is sleek, but the inside has a wavy ribbon with clear rhinestones. 2 1/4" tall by 1 3/4". The sturdy safety clasp works well but is a little bend that does not interfere in using. Other than the pin stem, the brooch is in excellent condition. Marked Castlecliff sterling. Carroll in Jewelry 101, page 140, writes Castlecliff sterling is a good investment.
