Vintage 16k Yellow Gold Amethyst Cube Modernist Ring

A 10mm cube cut amethyst forms the sculptural focus of this Modernist ring, its broad polished planes revealing lavender-purple color variation and visible internal inclusions. A straight gold bar crosses the stone’s face and continues into angular shoulders, creating a strong horizontal line against the cubic form. A small rectangular gold tab accents an adjoining face, while the restrained mounting leaves much of the amethyst exposed. The squared shoulders transition into a slender band, balancing the stone’s volume with an open, architectural profile. This emphasis on geometry, exposed material, and minimal ornament reflects the ring’s Modernist character.
