A halo ring surrounds the center diamond with a frame of small stones. It is one of the most effective ways to make a diamond look bigger and brighter for a modest cost.

A classic halo sits around the stone; a hidden halo sits beneath it; a double halo adds two rings; a floating halo lifts the frame for a lighter look.
A halo of small diamonds can make the center appear roughly a half-carat larger, depending on melee size and stone shape.
Halo accents usually add hundreds to a couple thousand dollars — far less than moving up in center-stone carat weight.
Pros: size, sparkle, protection for the center. Cons: more small stones to maintain, and some halo rings need a shaped or matching wedding band.
No. Classic halos remain popular, and hidden halos are currently one of the most requested styles.
Not when proportions are right. Thin halos with well-matched melee look elegant; a halo that is too wide can overpower a small stone.
Often not with a straight band. Many buyers choose a curved or notched band, or a hidden halo that leaves room below.
Round, oval, cushion and pear are the most common; square and emerald halos give a crisp, geometric look.
