Abstract: A method of setting precious stones in jewelry includes providing a metal support element of U-shaped cross section with two lateral bands separated by a central band and defining between them a channel, providing holes in the lateral bands and placing the stones into the channel and securing the stones in place in the channel with a wire passed through the holes from one band to the other across the channel.
