AI Item Analysis

·AI can make mistakes·Verify before acting
This piece is a vintage three-stone ring crafted in 14K yellow gold. It features three oval-cut cabochon opals arranged vertically on the finger, with the center opal measuring approximately 8.5mm x 6.25mm. The opals exhibit a vibrant play-of-color, predominantly displaying iridescent green and turquoise flashes against a milky white body color. Interspersed between the opals are four small round-cut accent diamonds, arranged in pairs of two, providing additional brilliance. The stones are held in place by traditional prong settings, a hallmark of mid-to-late 20th-century jewelry design. The ring is a size 5 3/4 and shows signs of being a legacy piece, with a slight patina to the metal surfaces and minor surface wear consistent with age. The opals appear well-preserved without significant crazing, though light surface scratches may be present upon magnification. The craftsmanship indicates a commercial-quality fine jewelry production, likely dating from the 1960s to 1980s, characterized by the substantial prong work and the specific arrangement of the auxiliary diamonds.

AI Appraisal Report

·AI can make mistakes·Verify before acting
Upon visual examination of this vintage three-stone ring, I have identified it as a 14K yellow gold piece featuring three oval cabochon opals and four accent diamonds, consistent with mid-to-late 20th-century commercial fine jewelry (circa 1960s-1980s). The primary value driver is the triple-opal setting; the center stone's dimensions (8.5mm x 6.25mm) are substantial enough to command attention. The play-of-color, described as vibrant green and turquoise, adds desirability, as 'dead' spots in opals significantly lower value. The condition appears commensurate with age; the slight patina on the gold is expected, and the lack of visible crazing (cracks due to dehydration) in the opals preserves the integrity of the stones. In the current secondary market, there is steady but niche demand for vintage opal jewelry. While not rare, this specific vertical three-stone configuration is a classic 'navette' style that appeals to vintage collectors. Comparable sales for similar 14K commercial-grade opal rings typically fall within the $400 to $700 range, depending heavily on the intensity of the opal's fire in person. However, this appraisal is limited by the nature of photographic examination. To provide a definitive insurance replacement value, I would require a physical inspection to verify the gold karatage via acid or XRF testing and to confirm the diamonds are natural rather than synthetic simulants common in this era (such as cubic zirconia or white spinel). Additionally, microscopic inspection is necessary to ensure the opals are solid stones rather than doublets or triplets, which would reduce the value significantly.
