The Start

Judith and her husband Jack Rosenberg created the company Judith Jack in 1969 when they realized there was very little marcasite estate jewelry available.  They had been selling antique pieces, and they could not keep up with the demand for this beautiful victorian-inspired jewelry from their buyers.    Exquisite style and quality made Judith Jack the leading marcasite fashion jewelry brand, leading Judith to be named the queen of marcasite in the U.S.

The Jewelry


Shop for Judith Jack Earrings

Judith Jack jewelry is generally made of Sterling silver with Marcasites, just like these cute earrings.  The jewelry is crafted with marcasite pieces, faux pearls, and sunray crystals hand set in sterling silver and hand polished.  Some designs manufactured are replicas of antique styles with sterling silver base metal. Marcasite, when cut with a flat bottom and many facets, shines like a small diamond.  Her jewelry lines include earrings, pins, pendants, rings, charms and bracelets in Victorian, Edwardian, Art Nouveau, Art Deco and retro styles.  Some of the jewelry made is limited in quantity and prices are quite high.  Judith Jack jewelry is marked with a “double JJ in a triangle”.
