The San Bernardino square antique Art Deco diamond engagement ring with a shimmering, sparkling half carat old European brilliant cut center. Filigree throughout and bordered by 4 calibre' sapphires in a geometric 18k white gold highlight this original setting. The experience of wearing an authentic circa 1920 Jazz Age treasure is sublime.


Why you'll love it: The attention to detail is wonderful; openwork, milgrain, pierced scrolling and hand engraving. The shoulders embellished with abundant character. The low profile setting, a scant 5.5mm rise above your finger makes this vintage heirloom ideal for everyday wear.
