Buying guide

How an infinity band is shaped

An infinity band has two strands that cross and loop near the center, tracing a figure-eight line. The curve adds movement to the ring and lets the band hug the center from each side. In this collection, most designs set pave lab-grown diamond accents on one or both strands, and the rest leave part of the twist in plain metal for contrast.

Styles to compare

  • Solitaire with a twisted band: the center sits alone, with all the detail in the band.
  • Infinity halo: a halo of accents frames the center above the twist.
  • Crossover and interwoven bands: strands that wrap past each other for a bolder line.
  • Split shank: rails that open near the head.

Every design is also made for a fancy blue, yellow, pink or green center, and some for a black center.

Metals and price

Gold comes in 10K, 14K or 18K, in white, yellow or rose. Platinum is dense and stays white. Silver is the most affordable choice. Settings start under $400, and most fall between about $1,150 and $1,500. That price covers the setting; the center is priced when you choose it.
