A bright and brilliant vintage round brilliant cut diamond, weighing one-and-a-quarter-carats, fills a vibrant royal blue frame of calibre-cut sapphires and burgundy red rubies in this classic Art Deco style 'jigsaw' or 'halo' ring, hand-fabricated in white gold in faithful emulation of 1920s-30s Art Deco style. Strikingly sparkling and stunning. The diamond is original to the period. The crown measures just shy of 1/2 inch, the tapered ring shank is currently size 6 1/4 and is sizable at no cost.
