Bypass Rowing Blades Adjustable Ring Made by Rubini Jewelers.

Sterling Silver. This design is bold enough to be recognizably rowing, but also big enough that the blades morph into a design. Each of these two blades measures about 10mm long (~1/3 inch). Ring is shown on a size 7 finger.

Matching bracelets B.85, B.53. Matching earrings E.62
