Georgian Guilloche Enamel and Diamond Brooch
Reminiscent of the work of Faberge, this thoroughly exquisite early 19th century treasure sparkles in the center with a 0.65 carat antique cushion-cut diamond dramatically set against deep cobalt blue guilloche enamel, encircled in turn by a graduated frame of glittering antique cushion-cut diamonds. When at rest, this pristine collectible Georgian jewel resides in its original fitted leather box signed: Collingwood Jewellers Ltd 46 Conduit ST W. (London). 1.90 carat total diamond weight, 1 inch diameter.
