Here is one of the most distinctive designs we've come across in an Art Deco engagement ring from the 1920s-30s. The striking hand pierced scaffolded mounting, die-struck and hand finished in platinum, culminates in a bright-white and sparkling European-cut diamond weighing .40 carat. The scintillating stone beams from between split diamond-set shoulders accented north and south with a pair of calibre sapphires, and east and west with diagonally set baguette diamonds. Decorative hand engraving adds the finishing flourish to this stunning, one-of-a-kind Jazz Age jewel. .72 carat total diamond weight. Currently ring size 5 1/2.
