Vintage Opal and Diamond Halo Cluster Ring

This is an elegant vintage-style halo cluster ring featuring a central oval cabochon white opal. The central opal displays a milky white base body color with subtle pinfire play-of-color, predominantly showing flashes of green and hints of violet/blue. The opal is securely set within a surrounding 'halo' of approximately twelve to fourteen small round-cut stones, which appear to be diamonds, set in individual collets or a shared-prong arrangement that creates a scalloped outer edge. The metal appears to be yellow gold for the shank (band), while the stones are set in a white metal—possibly white gold, platinum, or silver—which was a common technique in the late Victorian through Mid-Century periods to enhance the brilliance of the stones. The shank is a delicate, thin band that tapers slightly as it meets the head of the ring. Regarding condition, the opal shows a smooth surface without visible crazing or significant chips, though there is a soft patina of fine surface scratches on the metal consistent with age and regular wear. The style is reminiscent of late 19th-century Victorian aesthetics but could be a mid-20th-century revival piece. The high-domed cabochon and the precision of the cluster setting indicate quality craftsmanship, reflecting a timeless and classic jewelry design.
