Buying guide

How an infinity band is shaped

An infinity band crosses over itself on the way to the center, forming a figure-eight loop or a twisted ribbon. Most settings here add pavé lab-grown diamond accents along the crossing strands, so the band sparkles as it turns. Some are crossover twists, where two strands wrap past each other; others use a smooth ribbon shape.

Solitaire or halo

A solitaire infinity ring keeps the blue center on its own, with all the movement in the band. This is the simplest way to show off the color. A halo setting surrounds the center with small accents, which frames the blue and makes it look larger. A split shank opens the band near the center for a wider, more open look.

Metal and price

Gold comes in 10K, 14K or 18K, in white, yellow or rose. White gold and platinum keep a blue center cool and bright. Yellow and rose gold give a warmer contrast. Silver is the most affordable choice. Settings start under $400, and most are between about $1,150 and $1,550. The price is for the setting only; the center is priced when you choose it.
