MAGNIFICENT and MASSIVE 14k yellow gold antique late Georgian hand-painted on porcelain portrait brooch pin with stationary bail on back for use as a pendant. The subject is Georgiana Cavendish Duchess of Devonshire, Measures 2-3/4" x 2-1/4" x 3/8" thick. With heavy thick construction and applied scroll work. The portrait is under glass and measures 2-1/16" x 1-11/16". A beautiful portrait of a woman wearing a large black feather plumed hat and holding a single rose in soft shades of blue, green, black, gray, and white, with touches of pink. High magnification reveals small individual brush strokes, although I can see no signature. The back has a piece of brown silk, also under glass, most likely for use as a hair locket memento. The findings on the back are original, long slightly curved white metal pin stem, simple C shaped clasp with bottom extension (helps to act as a stop or a safety when worn), long hinge tube assembly. In outstanding exceptionally well babied condition, only ever so slight age appropriate wear. I have never disassembled this and it looks as if it has never been apart, but the construction looks top notch. Circa early 1800s.
Georgiana Cavendish, Duchess of Devonshire (née Spencer) 7 June 1757 – 30 March 1806, was the first wife of William Cavendish, 5th Duke of Devonshire, and mother of the 6th Duke of Devonshire.
