At 2.3 mm, this Nouveau-fit wedding band is thicker than most men's gold rings, and this decadent European design is simply brilliant in 18K white gold. This ring is a modern-day classic, with a domed profile, polished finish, and comfort fit design inside. Comfort-fit means the inside edges are gently curved and less of the ring touches the finger. And like every designer ring, it has a Lifetime Guarantee! Comfort-fit rings should be ordered 1/2 size smaller!
