American designer and author Karen Del Pellegrino lives and works in New Jersey. Her Shapeways shop, Silvergence, is earning a reputation as the place to go for Zombie, Klingon or Cat jewelry. Her most wanted pendants are festoons with rings or openings on both sides, through which chain or cord can be attached. Festoons usually function as the centerpiece of the necklace and Karen offers designs that enable her customers to add beads and findings to create truly unique one of a kind necklaces.
