Lisner Jewelry of New York

From Collector's Weekly:  For nearly 30 years after its 1904 founding, Lisner imported and sold Elsa Schiaparelli's Parisian jewelry in the United States. In the '30s, the company achieved a higher profile by finally selling its own designs that employed Dupont's new colored acrylic plastic called Lucite, as well as clear and colored rhinestones (particularly aurora borealis) and lava stones, as well as chromed, silver-plated, and black japanned metal.
