A classic early 20th century French design, the tourbillon - or twister - ring speaks to both the movement and whiplash lines of Art Nouveau design, and to the turn to more symmetry in Belle Époque pieces. Diamond-studded, milgrain-framed, and drawing your eye to the prominent culet of the old Euro at its heart, this ring has a hypnotic effect and will be sure to hold you under its sway.
