Antique Opal Ring Appraisal

Oval Opal and Diamond Halo Ring

The item is an oval opal ring with a diamond halo, likely set in white gold or platinum due to its silver-toned appearance. The central gemstone is a cabochon-cut oval opal, exhibiting a milky white body color with subtle hints of play-of-color, which appears to be pastel or iridescent flashes rather than strong, vibrant hues. It is surrounded by a halo of approximately 14-16 small, round brilliant-cut diamonds, each appearing to be about 1-1.5mm in diameter, set closely together to form a sparkling frame around the opal. The setting style for the diamonds appears to be either pave or bead set, where small prongs or beads of metal hold the stones in place. The ring band (shank) is visible in portions, appearing as a simple, unadorned band. The metal exhibits a bright, reflective surface, consistent with white gold or platinum, and appears to be in good condition with no obvious signs of significant scratching, tarnishing, or discoloration from the visible angles. The opal itself seems smooth and intact, without noticeable chips or cracks from this image resolution. There are no visible maker's marks or signatures, though these would typically be found on the inner band. The overall design suggests a classic or vintage-inspired aesthetic, possibly dating from the mid-to-late 20th century or a modern revival of such styles. The craftsmanship appears to be of good commercial quality, with the stones evenly set and the overall structure seemingly robust.
