James Emmett Caldwell established the jewellery company bearing his name in 1839 in Philadelphia, Pennsylvania. Having trained as a silversmith in New York, Caldwell supplied Philadelphia’s elite with silver, jewellery and objets d’art. By the turn of the century, the company became known for their gem-set Art Nouveau jewels, and to this day remain one of the premier American jewellers who worked in this mode. In 1916 the company moved locations to Chestnut Street, Philadelphia’s most fashionable street. In the 1920s the firm shifted gears to produce exceptional pieces in the Art Deco style.
