14k Yellow Gold Mexican Cantera Opal Ring

A sophisticated cocktail ring featuring a prominent round cabochon Mexican Cantera Opal centrally mounted in 14k yellow gold. The opal measures approximately 12mm in width and is characterized by its unique formation where pockets of fire opal are encased within their natural brown rhyolite host matrix. The gemstone displays a vibrant play-of-color, showcasing brilliant flashes of cobalt blue, violet, and emerald green against an earthy reddish-orange background. The ring is constructed with a comprehensive gross weight of 5.5 grams and is a size 9. The setting is highly decorative, featuring a concentric bezel with a twisted rope-texture border. The shoulders of the ring exhibit intricate openwork filigree and scrollwork designs, adding a classical or vintage-inspired aesthetic. The metal shows a high-polish finish, indicating excellent maintenance with no significant visible wear, scratches, or thinning of the shank. The craftsmanship reflects high-quality bench work, particularly in the symmetry of the bezel and the depth of the textured gold accents. This piece likely dates from the late 20th century to contemporary times, blending the natural, rugged beauty of the Mexican host rock with refined goldsmithing techniques.
