Swarovski Aurora Borealis Crystal Ring

This is a statement ring featuring a prominent faceted crystal or glass centerpiece. Based on the provided context, it is likely a Swarovski crystal ring, known for their precision-cut lead crystal. The stone is a large, rectangular cushion cut, presenting a striking iridescent play of colors, primarily displaying hues of green, blue, and purple when light reflects upon it, indicative of an Aurora Borealis (AB) coating or similar effect. The facets are large and clean, suggesting good optical clarity. The setting appears to be a polished silver-tone metal, likely rhodium-plated base metal or sterling silver, forming a simple bezel or basket setting around the large stone. The band is a slender, polished metal, possibly a double shank or split shank design, though only the upper portion near the stone is clearly visible, forming a clean, modern aesthetic. There are no immediately visible marks or engravings on the visible parts from the provided angle. The ring appears to be in good condition with no obvious chips or major scratches on the stone, and the metal shows a bright, reflective surface, indicating minimal wear or a recent polishing. The craftsmanship appears to be commercially produced but well-finished, typical of a brand like Swarovski. The overall design suggests a contemporary style, likely from the late 20th or early 21st century.
