Provenance History
Likely acquired via a private high-end retailer. No visible hallmarks or maker's marks are discernible from the perspective provided.
Art Historical Significance
Represents the enduring legacy of the 'Emerald Cut,' which gained prominence during the Art Deco era (1920s) for its sophisticated 'hall-of-mirrors' effect, departing from the typical brilliance of round cuts to showcase stone purity.
Notable Features
High-quality step-cut faceting on the center stone; the use of tapered baguettes creates a visual bridge between the center stone and the band, elongating the appearance of the wearer's finger.
Condition Issues
Minor surface abrasions on the metal setting (scratches); potential for slight loosening of prongs typical of daily wear; needs professional cleaning to remove oils.
Conservation Recommendations
Professional ultrasonic cleaning, prong tightening/retipping to ensure stone security, and rhodium plating if the metal is white gold.
