18K Sunburst Signet Ring with Diamond and Onyx
The sunburst pattern radiating from this ring's diamond center belongs somewhere between the geometric revivals of the 1970s and the architectural boldness of the 1980s, when traditional forms could be reimagined rather than simply repeated. The design takes its cues from Art Deco's obsession with rays and radiance but executes them with late-century precision, each line machine-engraved to catch light at calculated angles. The onyx creates negative space, darkness that makes the diamond appear to float. At nearly 6 grams of 18-karat gold, it has substance without ostentation. The hallmarks include a 750 stamp and a maker's mark—two X's in a circle—though the workshop remains unidentified.
Rays for days.
