The invention concerns a method of setting a plurality of stones each having a culasse, a crown and a girdle in a metal support element. The method includes the steps of milling a groove on a first face of the support element; piercing from a second face of the support element, opposite to said first face, a plurality of holes each having a diameter substantially corresponding to the diameter of the girdle of the stone that it will receive, such that each hole opens into said groove and the bottom of each hole forms a support wall for the crown of the stone, forming grains in the second face of the support element in proximity to the support walls, setting the stones in place in the holes such that the crown of each stone abuts against the support wall of the hole thereof, and pushing the grains against the culasse of each stone in order to fix the stones in said support element.
