Vintage Judith Jack sterling, marcasite, and amethyst brooch. This wonderful Art Deco inspired brooch made of sterling silver, is completely encrusted with sparkly marcasite stones, and features a square cut amethyst in the center. There is also fine mill grain detailing around all the edges. It has the feeling of wings, and is asymmetrical in design. The brooch measures 2 inches wide by 1.5 inches tall. The back is marked sterling with the JJ logo. Unfortunately, the photos just cannot capture the beauty of this piece - you will be pleased with how much more beautiful it is in person. It is in excellent condition.
