Showcasing bold mid-century German goldsmith craftsmanship, this substantial statement ring is forged in solid 835 silver with rich antiqued contrast. The prominent oval signet head centers a flat, high-polished tablet of natural black onyx (or French jet glass) bordered by an undulating, sculpted scalloped gallery with fluted border accents. Flowing seamlessly into split, bifurcated shoulders and a sturdy tapered shank, the interior is stamped with the authentic 835 silver purity hallmark alongside a master silversmith rosette mark.
