AI Appraisal Estimate

This is a contemporary-style three-stone ring featuring a central oval-cut gemstone, likely a tanzanite or sapphire, flanked by two smaller round-cut accent diamonds. The central stone exhibits a deep violet-blue hue with visible facet patterns and some internal inclusions or surface abrasions. The side diamonds appear to be round brilliant or transitional cuts, set within substantial bezel mountings. The entire piece is constructed from what appears to be yellow gold, possibly 14k or 18k, finished with a matte or slightly brushed texture. The bezel settings are thick and protective, a hallmark of modern or artisan jewelry design. Regarding condition, there is visible wear on the metal surfaces including minor scratches and a slight dulling of the finish, which is consistent with regular use. The central stone appears to have some surface reaching inclusions or minor chips along the edges of the facets. The craftsmanship suggests a handmade or custom studio piece rather than a mass-produced item, evidenced by the slight irregularities in the bezel thickness. While no maker's marks are visible in this view, the style is reminiscent of late 20th-century to early 21st-century designer jewelry. The proportions of the band are substantial, indicating a durable construction intended for daily wear.

I have conducted a visual examination of this contemporary three-stone bezel-set ring. The central stone exhibits the characteristic pleochroism and deep violet-blue saturation associated with high-quality tanzanite, approximately 1.5-2.0 carats. It is flanked by two round brilliant accent diamonds estimated at 0.15 carats each. The mount is consistent with 18k yellow gold, displaying an artisan matte finish popular in late 20th-century designer jewelry. The condition is graded as 'Good,' noting visible surface abrasions on the tanzanite crown and slight wear to the bezel walls. These imperfections slightly depress the value compared to a pristine specimen. The current market for colored gemstones remains strong, particularly for tanzanite which is limited to a single source in Tanzania. The bespoke, handmade nature of the setting adds a premium for craftsmanship, though the lack of a visible designer hallmark limits its secondary market potential to its intrinsic material and aesthetic value. This appraisal is based on a high-resolution visual inspection and carries inherent limitations. I cannot definitively verify the gemstone's species or determine if any heat or fracture-filling treatments are present without gemological testing. A physical examination is required to verify metal purity via acid or XRF testing and to confirm the diamond color/clarity grades (estimated here as G-H color and VS2-SI1 clarity). Final valuation would be contingent upon confirming the tanzanite’s authenticity via refractometer and polariscope testing, as synthetic blue spinel or glass can mimic this appearance.
