Vintage Mother of Pearl and Marcasite Sterling Silver Band Ring

This is a wide-band statement ring, likely crafted from sterling silver, featuring a central rectangular inlay of white Mother of Pearl. The organic gem displays characteristic iridescence with a soft, creamy luster. Flanking the central stone on both sides are decorative panels set with small, rose-cut marcasite stones, which provide a metallic, glittery contrast. The silver work includes intricate milgrain detailing and geometric grid-like texturing beneath the marcasites, suggesting an Art Deco revival style popular in the mid-to-late 20th century. The band is substantial with a tapared design toward the back for comfortable wear. Notable condition issues include a visible tarnish or patina buildup in the recessed areas of the metalwork, which is common for aged silver. There are superficial surface scratches on the polished silver surfaces and the Mother of Pearl inlay. All stones appear to be intact without heavy chipping, although some marcasites show dullness from age. No maker's marks are visible in the provided image, but the craftsmanship indicates a mass-marketed boutique jewelry piece.
