AI Appraisal Estimate

This is a luxury designer ring from Konstantino, an artisanal Greek jewelry house. The piece features a striking elongated marquise or navette-shaped face, measuring approximately 1.25 to 1.5 inches in height. The central focal point is a hammered, high-carat yellow gold plate (likely 18k), which exhibits a 'martelé' texture that catches light dynamically. This gold inlay is bordered by a meticulously detailed sterling silver frame showcasing classic Byzantine-inspired engraving, including rope-twist motifs and small circular granulation. The shoulders of the ring transition into a wide band, deeply carved with scrollwork and geometric patterns characteristic of Konstantino’s Neo-Classical style. In terms of condition, the silver displays a rich, intentional oxidation (patina) within the recessed areas to enhance the architectural depth, while the gold center remains bright. There are minor surface scratches consistent with gentle wear, but no significant deformation or loss of detail is observed. The craftsmanship level is high, indicating a handcrafted origin in Greece, likely from the late 20th to early 21st century. The combination of mixed metals and heavy tactile ornamentation is a signature quality indicator for this brand.

Based on the visual examination of the provided images and descriptions, I have appraised this mixed-metal designer ring attributed to Konstantino. The item presents an elongated marquise face featuring a hammered 18k yellow gold center surrounded by intricately engraved sterling silver with Byzantine and Neo-Classical motifs. The ring appears to be in very good condition, showing minor surface scratches consistent with gentle wear and a deep, intentional patina in the silver recesses that highlights the detailed scrollwork and granulation. The craftsmanship and design language are highly consistent with authentic Konstantino pieces, known for handcrafted quality from Greece. The secondary market for Konstantino jewelry is robust, with strong demand for their signature 18k gold and sterling silver mixed-metal designs. Comparable rings from this maker typically sell in the $450 to $650 range at auction or through high-end estate jewelers, depending on ring size and specific collection desirability. Factors positively impacting the value include the bold, elongated statement design and the distinct hammered gold inlay. Please note that an appraisal based solely on images has limitations. Full authentication and definitive valuation would require an in-person physical inspection to verify the metal purity through acid or electronic testing, confirm the ring size, assess the exact weight, and examine the manufacturer hallmarks and metal fineness stamps (e.g., '925' and '750') located on the interior of the band.
