AI Appraisal Estimate

This is a three-stone 'trilogy' style ring featuring three oval-cut blue sapphires, each surrounded by a pavé-set halo of small brilliant-cut white diamonds or diamond simulants. The stones are set in a white metal mount, likely platinum, white gold, or sterling silver, and are mounted on a simple band. The central sapphire appears slightly larger than the two flanking stones, creating a graduated aesthetic. The sapphires exhibit a deep, royal blue saturation with visible facet edges, suggesting they are either natural or high-quality synthetic stones. The halo settings use multiple small prongs to secure the accent stones. In terms of condition, the ring appears to be in good estate condition, though light surface scratches on the metal band and slight dullness in the accent stones suggest light previous wear. The design is contemporary, likely dating from the late 20th century to the early 21st century, emulating classic Victorian and Edwardian cluster styles. The craftsmanship appears solid with well-aligned prongs and symmetrical settings, though without a hallmark, the exact metal purity remains unverified.

I have conducted a visual examination of this three-stone 'trilogy' sapphire and diamond halo ring. The piece exhibits a contemporary design inspired by Edwardian aesthetics, featuring three oval-cut sapphires with a rich, royal blue saturation. The graduated arrangement and pavé-set halos are hallmarks of high-quality estate jewelry. Based on visual indicators, the stones appear to be natural sapphires, though the presence of heat treatment or synthetic origin cannot be ruled out without microscopic inspection. The metal, while currently unhallmarked in the imagery, displays the luster and wear patterns consistent with 14k or 18k white gold. The market for trilogy rings remains robust, driven by their sentimental 'past, present, future' symbolism. Comparables for mid-tier sapphire rings in precious metal settings typically fall within this range, though the lack of visible hallmarks and lack of stone certificates slightly tempers the valuation. Factors impacting value include the symmetry of the halos and the saturation of the center stone. Limitation Note: This appraisal is based solely on digital images. A definitive valuation requires in-person testing to confirm metal purity (via acid or XRF testing), sapphire origin/treatment (via gemological laboratory report), and diamond authenticity (via thermal conductivity testing). Provenance documentation or original sales receipts would further solidify the item's market value.
