A confident mid-century gentleman's tank-form ring in 14k yellow gold, the broad rectangular crown set across most of the face with a rounded tampered baguette polished black onyx panel that gives a deep matte-jet ground for the stone work. Down the left long edge runs a vertical line of five graduated round brilliant diamonds channel-set into a clean white-gold trough, the row reading as a sharp band of light against the black onyx. The onyx is bezel-collared in yellow gold along all four edges with a fine knife-edge rim, and the construction is solid and squared throughout.
