Emerald and Diamond Ballerina Halo Ring

This is a vintage-style ballerina-set cocktail ring featuring a central rectangular emerald-cut green emerald. The emerald displays a saturated medium-green hue with visible natural inclusions (jardin), typical for this gemstone species. It is held in place by four corner prongs. Surrounding the center stone is an undulating 'ballerina' style halo consisting of approximately 22 tapered baguette-cut diamonds on the upper and lower arcs, further accented by several marquise-cut and round brilliant diamonds on the lateral sides. The setting appears to be crafted from either 14k or 18k white gold or platinum, showing a high-luster silvery finish. The construction is complex, with a multi-level wire-work gallery visible beneath the stones to support the flared arrangement. Regarding condition, the metal shows light surface abrasions consistent with moderate wear. The emerald appears to have slight surface-reaching fissures, which is common. The ring lacks visible hallmark stamps in this view, but the craftsmanship suggests a mid-20th-century aesthetic (circa 1950s-1970s). The stones are securely set, although a professional cleaning and prong inspection are recommended to ensure long-term integrity.

I have conducted a preliminary visual appraisal of the Emerald and Diamond Ballerina Halo Ring. The piece is a classic mid-20th-century cocktail ring. The central emerald displays the desirable medium-green saturation and 'jardin' typical of Colombian or Zambian origins. The ballerina setting, popular in the 1950s-70s, features approximately 1.50 to 2.00 carats of tapered baguette and marquise-cut diamonds. While the craftsmanship is superior, the surface-reaching fissures on the emerald and light metal abrasions indicate a 'Fine' condition grade, though not 'Mint'. The market for vintage ballerina rings remains strong among collectors of mid-century glamour, with demand heavily weighted by the clarity and origin of the center stone. Because this appraisal is based on photographic evidence, there are significant limitations. I cannot definitively verify the metal purity (14k, 18k, or Platinum) or the exact carat weight and color grade of the diamonds. Most importantly, I cannot determine if the emerald has undergone stability treatments like oiling or resin filling, which can fluctuate value by 30-50%. A full authentication requires a physical inspection to test for metal hallmark verification, use of a refractometer for gemstone identification, and a laboratory report from GIA or SSEF to confirm the emerald's geographical origin and treatment status. The provided value assumes a 14k-18k gold mount with natural, minimally treated stones.
