Indulge in the swoon-worthy romance with hidden halo round engagement rings that steal the spotlight from every angle, not just the top. A hidden halo is a circle of diamond clusters below the center diamond, allowing your round stone to pop up beautifully, giving the illusion of a larger center stone than its actual carat size. This ring is an absolute heartthrob due to its design perfectly befitting those who love the idea of mystery in romance.
