Yvonne Léon - Un Deux Trois 9-Karat Yellow And White Gold Diamond Ring - 7

Yvonne Léon's ring is aptly named 'Un Deux Trois' - which in French translates to 'one, two, three' - after the trio of linked bands it's comprised of. It's handcrafted from 9-karat yellow and white gold and features completely different styles - one etched with textural lines, another inlaid with a row of light-catching diamonds, while the last is smooth and has the slimmest profile. Wear it on your index or middle finger.
