The architectural aesthetics of the 1920s


The Art Deco movement redefined the conventions of jewellery design by replacing organic curves with strict geometric precision. This structured approach is evident here in the bold colour contrast between the central gemstone and its setting. This pre-owned piece centres on an old-cut round diamond, estimated at 0.30 carats, held in a closed-set setting. The use of 950 platinum gives the piece a cool grey hue and ensures the strength of the openwork sections.


Architecture and jewellery craftsmanship


The structure of this ring is based on an upper plate with cut corners. The central diamond is framed by a halo of blue sapphires, custom-cut to fit edge-to-edge. The band is divided into two textured sections inlaid with small diamonds set using a grain setting. The lower setting features a scroll motif, maintaining a generous visual volume whilst ensuring the ring feels light on the finger. All the edges are finished with a continuous millegrain setting.


Why choose this second-hand ring


Acquiring an Art Deco-inspired creation on the second-hand market is a discerning aesthetic choice. Reproducing such a high level of detail – involving the calibrated cutting of the sapphires and the hand-engraved openwork in the platinum – would require a significantly higher budget for bespoke manufacture. This ring offers direct access to exacting artisan craftsmanship, with a tangible presence on the finger that ensures it sits perfectly.


Contents and condition


The piece is a size 53. The 950 Pt hallmark is engraved on the inside of the band. Our workshops have carried out a full inspection of the settings and polished the mount to ensure the integrity of the design. This piece will be presented to you in a The Swiss Collector presentation box.
