AI Appraisal Estimate

This jewelry item is a vertical pendant featuring a large center gemstone and three small accent stones. The primary stone is an aquamarine, characterized by its translucent light blue color and an octagonal emerald-shaped step cut. The stone is held in a four-prong setting made of yellow gold. Above the main stone sits a horizontal bar set with three small, round brilliant-cut diamonds (or diamond simulants) in individual bead settings, creating an elegant crown-like topper. The pendant is finished with a simple, polished rabbit-ear bail. In terms of condition, there is prominent surface scratching and scuffing visible on the table and crown facets of the aquamarine, suggesting regular wear or contact with abrasive surfaces. The metal shows some dulling of the polish, though no major structural damage or missing stones are apparent. This style is consistent with late 20th-century semi-fine jewelry, likely from the 1980s or 1990s. The craftsmanship is commercial grade, featuring common prong work and a standard decorative bridge between the bail and the gemstone cage.

I have conducted a visual inspection of this emerald-cut aquamarine and diamond pendant in yellow gold. The primary gemstone exhibits the characteristic pale blue hue of Beryl, estimated at approximately 4.0-5.0 carats. The three accent diamonds are of commercial quality, likely totaling 0.05 carats. The most significant factor impacting value is the condition; the aquamarine shows heavy surface scuffing and facet junction wear, which diminishes luster and would require professional recutting or polishing to restore full brilliance. The yellow gold mount is standard commercial casting from the late 20th century. In the current secondary market, such pieces are valued primarily for their gold content and decorative appeal rather than rarity. The estimate reflects the 'fair' condition of the center stone. Please note that this appraisal is based on photographic evidence alone. Without physical testing, I cannot definitively confirm if the center stone is natural, heat-treated, or a synthetic spinel simulant. A full authentication would require a refractometer test for light dispersion, microscopic inclusion analysis to determine origin, and a gold acid or XRF test to verify the karatage of the mounting. Documentation of provenance or an original sales receipt would further support this valuation.
