The channel setting is a secure way to set smaller diamonds in a row into the band of the ring, making a metal channel of sparkling stones flush with the shank. Channel set rings feature accent gemstones, which are small diamonds or other gemstones incorporated into a ring to add a touch of sparkle and glamour.
The diamonds, or other gemstones, are set closely together into the grooves of the channel, formed by two strips of precious metal. Grooves on both walls hold the diamonds securely in place. When round diamonds are channel set, triangular-shaped spaces usually appear in the corners between the stones, creating a distinctive look. This setting can decorate the sides of the band or the entire band. This setting is also popular for wedding bands or stackable rings that feature only smaller stones and no centre stone.
Since there are no prongs, this setting is also a good option for a snag-free and secure design. However, because there is more metal around the stones, slightly less light is visible in comparison to a bar or prong setting.
