Fashioned from brilliant tourmaline stones so deep in its green color as to resemble hard candy, this Art Deco–style brooch by J. E. Caldwell & Co. captures light with every movement, shifting from flash to shimmer under sun or lamplight. The three gemstones are of a distinct green tourmaline known as “Elbaite,” which takes its name from mines on the Italian island of Elba. Diamonds articulate the edges and anchor the “knot” at center, heightening the sense of luxury. Carved with folds that mimic silk, the stones offer the illusion of soft fabric—an inventive dialogue between material and motif.
Founded in 1839 by James Emmott Caldwell, J.E. Caldwell & Co. became one of America’s most distinguished jewelry houses and a pillar of Philadelphia’s historic Jewelers’ Row. Trained as a silversmith in New York, Caldwell supplied wealthy Philadelphians with fine European jewelry, silver, and objets d’art before establishing his own firm, which flourished in Center City for more than 160 years. The company gained renown for its elegant silver services, presentation pieces, and finely detailed jewels that exemplified exceptional craftsmanship and classical refinement. By the late nineteenth century, Caldwell was creating hand-fabricated Art Nouveau jewelry—graceful designs of women, vines, flowers, and insects worked in unusual gemstones and chased metal. In the 1920s, the firm embraced the streamlined geometry of Art Deco, producing some of the era’s most sophisticated American jewelry. Although changing fortunes led to later sales and closures, Caldwell’s legacy endures in its heirloom works and in Philadelphia’s reputation as a center of fine jewelry and metalsmithing.
