Fr0115 This is a vintage-style sterling silver statement ring featuring an oval green gemstone centerpiece highlighted by intricate marcasite stone embellishments. Design FeaturesCenter Gemstone: The focal point is a vibrant, translucent green oval faceted gemstone. This type of gemstone is typically a green onyx. Metalwork & Finish: The metal is 925 sterling silver that has undergone blackened finish. This deliberate patination darkens the recessed areas of the silver, creating a dramatic, antique contrast that highlights the detailed metalwork. Accent Stones: The band and the halo surrounding the central stone are encrusted with small, metallic-looking stones called marcasite. These are actually faceted pieces of iron pyrite commonly used in Art Deco and Victorian revival jewelry to provide a subtle, glittering metallic sheen. Band Style: The piece features a wide, multi-tier split shank design that spans across multiple rows, giving the illusion of layered bands tapering cleanly into a solid single band at the back.
