Judith Jack Sterling Silver Marcasite Drop Dangle Teardrop Stud Earrings! NWT! Absolutely beautiful and RARE!! Pictures are part of the description. 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. 5.7W
