Vintage Onyx & Diamond Men's Signet Ring 10K Yellow Gold Size 12

O.C. Tanner made this vintage 10-karat yellow gold men's signet ring as an employee service award for the Rayloc company, setting a square black onyx beside two round brilliant diamonds. The Salt Lake City firm built its name on corporate service awards, milestone pins, and school rings. The onyx rests in a stepped gold frame, and the diamonds share a narrow panel between two black-lined grooves. The broad, squared head sits flat and low across the finger while the shank narrows steadily toward the palm, which keeps this substantial everyday men's ring comfortable between the fingers.
