Oval Black Star Sapphire and Diamond Accent Gold Ring

This is a vintage-style ring featuring a central oval cabochon-cut black star sapphire, approximately 8mm x 6mm in size. The sapphire displays a distinct asterism (a four- or six-rayed star reflection) typical of this gemstone variety when viewed under direct light. The primary stone is held in a secure four-prong setting. Flanking the center stone are two small round brilliant-cut diamond accents, each set within a triangular gold shoulder. The band is crafted from yellow gold (likely 10k or 14k) and features a bypass or 'swirl' design where the shank curves around the center stone in a fluid, asymmetrical motion. The metal shows a warm patina and minor surface scratches consistent with regular wear, suggesting a mid-to-late 20th-century origin (circa 1970s-1990s). The craftsmanship is characteristic of commercial fine jewelry, with smooth polishing on the interior of the split-shank. No visible maker's marks or hallmarks are identifiable from the image, but the construction indicates a solid gold casting rather than plating. The condition of the sapphire appears good, with no overt surface chips or fractures visible on the crown.
