Vintage 10K Gold Onyx Signet Ring · Diamond P Initial · 1960s Men's Ring

A wonderfully distinctive vintage signet ring crafted in solid 10K yellow gold, featuring a rectangular black onyx stone panel accented with an applied gold letter “P” and a tiny diamond-set white metal detail.
 
The ring has a substantial architectural look, with deeply ribbed shoulders tapering into the band and a raised rectangular face. The combination of black onyx, gold initial and small diamond accent gives it a classic mid-century gentleman's ring feel.
 
The face measures approximately 11.95 x 15.65 mm, giving the ring plenty of presence without being overly large. At 6.9 grams, it also has a pleasing weight on the hand.
 
A particularly interesting vintage initial ring for someone with a P name—or simply a collector drawn to unusual mid-century signet rings.
