Oval Sapphire and Diamond Halo Ring in White Gold or Platinum

This elegant cocktail or engagement-style ring features a centrally mounted oval-cut natural blue sapphire. The sapphire exhibits a deep, saturated navy blue hue with visible pleochroism and is secured by four discreet prongs. Surrounding the center stone is a classic 'flower' or halo cluster composed of eight small round brilliant-cut diamonds or white-stone simulants, each set in an individual shared-prong arrangement. The metal appears to be a polished white alloy, consistent with white gold or platinum, showing a slim, rounded band (shank) that tapers slightly toward the head of the ring. The side profile reveals a basket setting that elevates the cluster to allow light penetration from below. In terms of condition, the metal shows light surface abrasions and minor scratches consistent with moderate wear. The sapphire shows some minor facet edge wear under magnification. There are no obvious hallmarks visible in the current view, but the design suggests a late 20th-century to contemporary manufacturing period, likely following the traditional Princess Diana-inspired cluster style. The overall craftsmanship displays commercial-to-fine jewelry quality with symmetrical stone placement and a high-polish finish.
