Tiffany & Co. Emerald and Diamond Wave Band Ring

This is a fine jewelry ring featuring a contoured wave or bypass-style band crafted in yellow gold, likely 18k based on typical Tiffany specifications. The ring is set with a central round faceted natural emerald of deep green hue, flanked by graduated round brilliant-cut diamonds. The gemstones are set in a channel-style or flush mounting that follows the undulating curve of the metal. The setting is robust, with a polished finish and thick walls, characteristic of late 20th-century designer fashion. Based on the style, this appears to be a vintage piece from the late 1980s or 1990s. The stones exhibit good clarity, though the emerald shows typical natural inclusions. Visible condition shows minor surface scratches and light wear on the gold band consistent with age and regular use. The overall craftsmanship is high-tier, featuring smooth transitions between the metal and the stones without snagging edges. While the maker's mark is not visible in the provided photo, the design language is consistent with Tiffany & Co.'s more architectural band series.

Upon visual examination of this Tiffany & Co. Wave Band, I find the craftsmanship consistent with the brand’s late 20th-century production. The piece features a high-purity yellow gold mounting (presumed 18k) utilizing a channel-set bypass design. The central emerald exhibits the desirable 'Jungle Green' saturation expected of Tiffany-sourced stones; although natural inclusions are present, they do not diminish the structural integrity of the stone. The flanking diamonds show excellent scintillation, likely grading in the F-G color and VS clarity range. The current market for vintage Tiffany architectural bands remains robust, as these pieces bridge the gap between daily wearability and high-fashion collectible. Comparables for similar multi-stone wave designs typically realize between $2,000 and $3,200 in retail boutique environments. The value is buoyed by the 'Tiffany & Co.' premium, which can add 40-60% over the raw intrinsic value of the gold and gemstones. Limitations: This appraisal is based on photographic evidence only. Authentication cannot be 100% definitive without a physical inspection of the hallmark stamps and a microscopic analysis of the emerald's inclusions to confirm origin and absence of synthetic fillers. To finalize this valuation for insurance purposes, I would require a physical examination to verify the metal's fineness via XRF testing and a review of any original sales provenance or a Tiffany & Co. blue box, which significantly impacts secondary market liquidly.
