A Promise, Perfected

Blue Diamond Channel Set Rings

A blue diamond channel set ring holds rows of lab-grown diamond accents between two walls of metal, leaving the fancy blue center you choose in the next step to sit above a smooth, bright band. Every design comes in ten shapes and in white, yellow or rose gold, platinum, or Silvadium, a tarnish-resistant sterling silver.

Buying guide

What a channel setting is

In a channel setting, small stones sit side by side in a groove cut into the band, held by the metal walls on each side instead of by prongs. Nothing sticks up to catch on sweaters or gloves, and the accents are well protected from knocks. That makes a channel set ring a practical choice for daily wear, with a clean line of sparkle that leads the eye to the blue center.

Styles in this collection

  • Channel set solitaires and side stone rings: the classic look, with the channel running along the shoulders.
  • Baguette channel bands: straight-sided baguettes for a crisp, geometric line.
  • Cathedral and vintage designs: raised shoulders or milgrain edges around the channel.
  • Halo, bezel and three stone options: a few designs add these around the center.

Metal, karat and price

Gold comes in 10K, 14K or 18K. White gold and platinum make a blue center look cooler and deeper, while yellow and rose gold add warmth. Settings start under $350, and most are between about $1,100 and $1,500. That price covers the setting only; the blue center is priced when you choose it.
