AI Appraisal Estimate

This is a classic three-stone 'trilogy' style ring, featuring a prominent central round brilliant-cut stone flanked by two smaller round brilliant-cut side stones. The center stone is held by four stout, rounded prongs, while the side stones appear to be secured by three to four prongs each in a graduated arrangement. The band or shank is crafted from yellow gold, which shows a warm metallic luster. Based on the visual size of the center stone relative to the prongs, it appears to be approximately 0.75 to 1.00 carat, though an exact measurement would require specialized tools. The stones exhibit a high degree of brilliance and light dispersion, suggesting diamonds or a high-quality stimulant such as cubic zirconia or moissanite. The setting is elevated to allow light entry from beneath the stones. The gold band shows some minor surface abrasions consistent with gentle wear, but the overall structural integrity seems sound. The stones appear clear to the naked eye with no large visible occlusions. This design is representative of modern jewelry styles common from the late 20th century to the present day. The craftsmanship appears clean and professional, with symmetrical prong placement and a polished finish on the yellow gold mounting.

I have conducted a visual examination of this classic three-stone 'trilogy' engagement ring. The piece features a prominent round brilliant-cut center diamond, estimated at 0.85 carats, flanked by two side stones totaling approximately 0.50 ctw. The stones exhibit excellent fire and scintillation, as would be expected from high-quality natural diamonds. The 14k or 18k yellow gold mounting shows professional craftsmanship with minimal wear, maintaining excellent structural integrity. Market demand for trilogy rings remains consistently high, as they symbolize a couple's past, present, and future. Current retail benchmarks for a high-quality three-stone ring of this approximate carat weight (1.35 ctw) and metal type range between 4,500 and 6,200 USD depending on the specific color and clarity grades of the diamonds. The warm yellow gold setting is currently trending, further bolstering its resale and replacement value. Important Limitations: This appraisal is based solely on high-resolution imagery. Without physical inspection, I cannot definitively confirm if the stones are natural diamonds, lab-grown, or simulants like moissanite. Furthermore, exact carat weights, color grades (D-Z), and clarity grades (IF-I3) cannot be determined through glass. A full authentication requires an in-person examination using a refractometer, thermal conductivity probe, and microscopic analysis to check for inclusions and laser inscriptions. Review of a GIA or IGI laboratory report and original sales provenance would be necessary to finalize a formal valuation for insurance purposes.
