A halo ring and a pave ring are two different types of settings for diamond rings. The primary difference between the two is the way that the diamonds are set. Here are the differences:
Halo ring:
A halo ring features one center diamond surrounded by smaller diamonds that create a 'halo' effect around the center stone.
The smaller diamonds in a halo ring are often set close together to create a seamless ring of sparkle.
A halo setting is designed to enhance the appearance of the center diamond, making it appear larger and more brilliant.
Pave ring:
A pave ring features small diamonds set closely together on the band of the ring.
The diamonds in a pave ring are set in tiny 'pockets' in the metal, so they sit flush with the surface of the ring.
The goal of a pave setting is to create a continuous sparkle along the band of the ring, rather than to enhance the appearance of a single center stone.
