Hidden halo: In a hidden halo design, the accent stones are strategically placed beneath the center stone, often at an angle. This arrangement contributes to the illusion of a floating center stone. The hidden accent stones provide additional sparkle and create a halo effect that is concealed from certain perspectives.

Cluster rings, on the other hand, are made using dozens of tiny diamonds all clustered together. They're cheaper because they're much much easier to make than solitaires. Those tiny diamonds are known as “smalls” in the industry, and they're often made from the leftovers of bigger diamonds.

Although variations can occur, most Halo engagement rings are solitaire rings. This means the halo surrounds a single diamond or gemstone. The diamonds in a halo are referred to as melee diamonds. They are typically between 0.01-0.02 carats (or smaller).

A halo diamond ring is a setting that has a center diamond in a collection of round pavé or micro-pavé diamonds. These pavé stones are beautiful because they flash with light and they also bring the focus attention to the center diamond. This creates interest and draws attention to the diamond engagement ring.
