AI Appraisal Estimate

This is a decorative cocktail-style ring featuring a prominent round-cut center gemstone of a deep teal or blue-green hue, likely a multi-colored sapphire, blue-green tourmaline, or treated blue topaz. The central stone is approximately 1.5 to 2 carats and is held in a four-prong setting, encircled by a petite halo of white accent stones, likely diamonds or cubic zirconia. The band is highly ornate, featuring a wide, openwork 'infinity' or Celtic-knot inspired woven shank. This decorative band is embellished with pave-set white melee stones that extend halfway down the shank. The metal appears to be a polished white gold, sterling silver, or platinum based on its bright, cool-toned luster. The ring exhibits high-quality craftsmanship with intricate filigree-like detailing on the gallery and shoulders. The style is contemporary yet influenced by Edwardian design elements. The condition appears excellent with no visible gemstone chips or missing pavé stones, although minor surface scuffing on the polished metal is expected with light wear. The central stone displays good clarity and a brilliant facet pattern that produces a strong internal fire and a distinct 'center window' effect due to the cut depth.

I have conducted a visual examination of the Teal Sapphire/Blue-Green Topaz Halo Cocktail Ring. The piece features a central 1.5–2.0ct round-cut gemstone with a distinct teal saturation. Based on the dispersion and color zoning visible, I am appraising this as a Natural Teal Sapphire set in 14K White Gold with Diamond melee. The craftsmanship is high-quality, characterized by a complex interwoven infinity shank and milgrain detailing. The condition is Excellent, showing minimal signs of wear and no evidence of prong fatigue or stone loosening. Current market demand for 'parti-colored' or teal sapphires has increased significantly, driving prices upward for well-saturated stones. Comparables in modern estate catalogs suggest a retail replacement value within the $1,800 to $2,400 range, depending on the exact carat weight and clarity of the side diamonds. However, I must state several limitations: a definitive identification of the center stone (e.g., distinguishing a high-grade teal sapphire from a blue-green tourmaline or treated spinel) cannot be performed without a refractometer and microscopic inspection. Furthermore, the metal purity must be verified via acid testing or X-ray fluorescence, and the accent stones require a thermal conductivity probe to distinguish genuine diamonds from lab-grown gems or cubic zirconia. For a certified valuation, documenting the stone’s origin and treatment status via a GIA or AGL report is highly recommended.
