Late-Edwardian/Early-Art Deco Diamond and Blue Enamel Circle Brooch
We've never seen anything quite like this fabulous one-of-a-kind masterpiece of jewelry art, dating back to the first or second decade of the twentieth century. Measuring 1 3/16 inches in diameter, the mesmerizing spirographic design of concentric arcs, reminiscent of 1960s pop-art, are set with tiny rose-cut diamonds glittering against a contrasting background composed of cobalt blue enamel (which we first mistook for lapis lazuli). Magnificently hand fabricated in platinum over 18K yellow gold in a masterful manner that would make Faberge proud. The central European-cut diamond weights .40 carat.
