A commanding statement of 1930s machine-age design, this substantial signet ring is crafted in solid 835 silver with a worn, authentic vintage patina. The bold, geometric crown features a large, custom-cut octagonal black onyx tablet, securely set within a stepped silver bezel. The broad, architectural shoulders are heavily detailed with deeply carved, tiered linear grooves—a classic hallmark of Art Deco styling. Please note that the silver exhibits natural surface wear and scratches throughout, and the onyx stone shows visible surface abrasions consistent with its age and history, which has been factored into the value. The sturdy, heavy-gauge band is clearly stamped with an authentic 835 silver purity hallmark on the interior.
