A 14k white gold man's diamond with black onyx bullseye ring by Birks from the late 1930s 1950. This vintage size 7 men's ring by Birks Canada has a central 21 point genuine diamond which has a round black onyx stone bezel set around the centre stone. It is stamped BIRKS and 14 K and another mark. The whole ring is white gold, and was custom made at Birks.
The ring comes with an independent gemologist's appraisal for $2000CAN. The diamond measures 21 points (measured in setting) and is SI-1 clarity and I-J colour. There are two quite minutes chips at the bezel, visible only with a loupe, and this was mentioned in the appraisal of $2000 CAD. The ring measures 5/16" across the top and it weighs a substantial 6.7 grams; it is in excellent condition with no chips, cracks, dents, bends, corrosion, losses, damage or repairs. It was photographed before being cleaned, so there are vestiges of surface grime visible in our photos.
