gold-toned gemstone ring in the style of a lapis lazuli floral cluster

This piece appears to be a vintage-style cocktail ring featuring a floral cluster design. The item is constructed from a yellow-toned metal displaying a textured, rope-like or granulation detail along the split shank and the bezels holding the stones. The primary decorative elements consist of several deep blue, polished gemstone cabochons shaped like petals, which display scattered golden pyrite inclusions characteristic of lapis lazuli. At the very center of the floral cluster sits a small, clear faceted gemstone that appears to be a diamond or a similar simulant set in white metal prongs. The overall condition shows minor surface wear and patina consistent with age and handling. There are no maker's marks, hallmarks, or stamps visible in the provided image; therefore, the material composition cannot be definitively established from the photograph alone. The owner provides user-attributed context describing the piece as a "real gold and lapis ring," but this claim remains unverified without physical testing and expert appraisal. The hedged naming is used because the exact metal purity and stone identity cannot be visually confirmed from an image. The stylistic execution suggests mid-to-late 20th-century costume or fine jewelry production, though further in-person inspection of inner band hallmarks would be necessary to determine origin and composition.

Based on what I can see in the photograph, this piece presents as a vintage-style cocktail ring featuring a floral cluster design with deep blue gemstone cabochons displaying golden pyrite inclusions resembling lapis lazuli, accented by a central faceted gemstone set in white metal prongs and a textured yellow-toned split shank. However, I can't verify from a photo whether the metal is solid gold or what the exact composition of the stones might be, as there are no visible maker's marks or hallmarks. Per user submission: attributed as a real gold and lapis ring. My appraisal value estimate of $450 to $750 is conditional and assumes that the owner's attribution regarding the materials is correct upon physical inspection. General market demand for mid-to-late 20th-century cocktail rings utilizing lapis and gold is steady among vintage jewelry collectors, influencing this range. If physical testing reveals the piece to be costume jewelry crafted from base metals and synthetic stones rather than solid gold and natural lapis, the value would decrease significantly, typically falling into the $50-$150 range. To confirm authenticity and material composition, a physical inspection, acid testing or X-ray fluorescence (XRF) for metal purity, gemological testing of the cabochons and central stone, and hallmark verification by a qualified professional would be needed.
