Another setting that can be used for any type of stone, the channel setting sees the goldsmith creating a channel - as the name would suggest - and then cut seats in it where the diamond will sit. After each diamond is placed in the new channel, the goldsmith secures the stones in place by hammering the upper sides of the channel walls.
With pavé settings, several small gemstones - usually diamonds - are set closely together, separated and held in place by small beads of the setting metal. This produces what resembles a continuous string of diamonds or other gems on its surface.
Similar to the Channel setting, the Bar setting sees that diamonds are set between bars, where they are first nested in grooves and then overlapped by metal using a hammering tool. Like the Tension setting, this also requires gemstones to have a Hardness level of 9 or above.
