Vintage Judith Jack sterling, marcasite, onyx and faux mabe pearl brooch. This outstanding, Art Deco style vintage brooch features a faux pearl, flanked by softly faceted black onyx stones, surrounded by marcasite. But the best part is the articulated marcasite studded fringe! It consists of 15 graduated pointed bars of marcasite, that dangle from the bottom of the pin, giving it beautiful sparkle with every movement. The camera just cannot capture the beauty of this brooch! It is 2.12 inches wide by 1.88 inches long. It is marked on the back with Sterling and JJ logo. This brooch is in perfect condition.
