    J.E. Caldwell & Co.: Based in Philadelphia, this American jewelry firm was founded in 1839 by James Emmott Caldwell, a trained silversmith. The firm sold silver objects, jewelry and giftware. After changes in ownership, the name officially became J.E. Caldwell and Co. in 1868. Their exquisite hand fabricated jewels are among some of the finest examples of American Art Nouveau craftsmanship in evidence. Throughout the 1920’s, they produced refined pieces of Art Deco jewelry for which the firm is still recognized. The business continues to service the Philadelphia area today.
