Buying guide

How a channel setting works

In a channel setting, small stones sit side by side between two walls of metal, with no prongs between them. The walls protect the edges of the stones and give the band a smooth surface that is less likely to catch on clothing. Here the channels hold lab-grown diamond accents, which run toward the lab-grown sapphire at the center: a channel set princess cut lab-grown sapphire and lab-grown diamond ring with a clean, structured look.

Band styles to compare

  • Channel-set solitaire: a single lab-grown sapphire above a channel band.
  • Tapered baguettes: rectangular lab-grown diamond accents that narrow along the band.
  • Pavé and baguette: mixed accents for more sparkle.
  • Bypass split shank: a band that divides and wraps past the center.

Color, size and price

Every design comes in lab-grown blue, pink or yellow sapphire. A lab-grown sapphire shares the chemistry of a natural sapphire and is 9 on the Mohs scale, hard enough for daily wear. Carat options run from 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. Prices start under $400 at the smallest size, and most rings cost between about $900 and $1,400 at that size.
