Art Deco 18K White Gold Diamond Ring · 1920s Filigree Engagement Ring

A beautiful Art Deco diamond ring in 18K white gold, dating to approximately the 1920s–1930s. This delicate antique ring is exceptionally detailed, with intricate pierced filigree, engraved shoulders and fine decorative work extending down the band.
 
At the centre is a round diamond measuring approximately 3.25 mm, set within a geometric octagonal frame characteristic of the Art Deco period. The openwork gallery and finely patterned shoulders give the ring an airy, lace-like appearance while the geometric centre provides that unmistakable Deco look.
 
The diamond has been tested with a Presidium diamond tester. Its estimated carat weight is approximately 0.12–0.14 ct based on its face-up measurement; the stone has not been removed from its setting for an exact weight.
 
The ring is stamped 18K.
