Vintage-Style Onyx and Marcasite Sterling Silver Statement Ring

This is an elongated oval statement ring crafted from 925 sterling silver, featuring a black onyx inlay surrounded by marcasite stones. The design is characteristic of the Art Deco Revival style, likely produced in the late 20th century (circa 1970s-1990s). The centerpiece is a polished, flat black onyx cabochon shaped in an oval. Overlaid on the onyx is a smaller central oval panel densely set with rose-cut marcasite stones. The entire assembly is further framed by an outer scalloped border of pavé-set marcasites, which provide a metallic, subdued glitter. The ring face is substantial in size, extending toward the knuckle, often referred to as a 'dinner ring.' The mounting is sterling silver, confirmed by the '925' hallmark mentioned in the context. The craftsmanship displays fine milgrain detailing around the stone settings, a technique used to add texture and vintage appeal. Condition-wise, the ring appears well-maintained with a natural dark patina in the recessed areas of the silver, which enhances the visual depth of the marcasite settings. There are no visible missing stones or significant chips to the onyx in the provided image. The shank is not fully visible but appears integrated into a solid, tapering band.
