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.
