She’s got Parisian angles and a center stone you can spot from across the bar.

Sourced just outside Paris, this bold midcentury cocktail ring is a masterclass in geometry and glamour. Crafted in platinum and 18K gold, it features 42 hand-set single-cut paste stones framing a knockout central crystal—all arranged in a stepped rectangular face that’s pure postwar drama.

Marked 750 with a partial French assay, this piece delivers all the hallmarks of 1950s French studio jewelry: architectural precision, cinematic sparkle, and unapologetic presence. A cocktail ring with architectural edge—and zero intention of staying quiet.
