Vintage 18K Yellow Gold Green and Blue Enamel 'Honeycomb' Dome Ring

This is a high-quality vintage dome-style ring, likely mid-20th century (circa 1960s-1970s), showcasing a sophisticated trellis or honeycomb pattern. The piece is constructed from 18K yellow gold (assumed based on color and style) featuring a wide, high-profile bombé or dome top. The design consists of a raised, beaded gold wire framework that creates diamond or lozenge-shaped cells. Each cell is meticulously filled with translucent 'basse-taille' style enamel in alternating shades of deep forest green and royal sapphire blue. The enamel appears to have a textured gold surface beneath it, which enhances light reflection and depth. The gold work includes a tapered, polished shank that widens significantly at the shoulders to support the decorative head. Notable features include the intricate 'granulation' effect on the gold lattice. While no maker's mark is visible in this specific angle, the craftsmanship is indicative of high-end European houses such as Tiffany & Co. (Schlumberger style) or Greek jewelers like Ilias Lalaounis. The condition appears excellent with no visible chips or cracks to the delicate enamel, though minor surface scratches on the gold shank suggest gentle previous wear. This style epitomizes the bold, textured gold aesthetic popular in mid-to-late 20th-century luxury jewelry.
