A magnificent and rare collector's piece of German vintage silversmithing by Blachian Antik Schmuck (BAS), this sculptural cocktail ring is cast in solid 925 sterling silver with deep contrast antique oxidation. The crown showcases a towering coronet bezel with fluted, serrated castle-like gallery walls cradling a massive, high-domed sphere cabochon of natural royal-blue lapis lazuli. The gemstone glows with vivid cobalt saturation, natural denim veining, and rich golden pyrite flecks. Supporting the crown is an organic, high-relief undergallery and wide shoulders sculpted as deeply veined acanthus leaves that wrap gracefully around the finger. The interior shank is clearly struck with the maker's hallmark "BAS" alongside an authentic "925" silver purity stamp.
