Abstract: The invention relates to a decorative part (1, 3, 5) including several stones (2) and a device (7, 7?, 47, 47?) for securing the stones (2) in relation to each other. According to the invention, the securing device (7, 7?, 47, 47?) includes a single electrodeposited base (9, 9?, 49, 49?) whose shape matches one part of the stones, thus allowing all the stones (2) to be attached in relation to each other without any stress, and the girdles (6) of the stones (2) are mounted edge-to-edge in relation to each other so that the single base is concealed. The invention also relates to the method for manufacturing a part (1, 3, 5) of this type.

Abstract: A decorative piece includes a support made of a material having no usable plastic deformation in which at least one hollow is arranged. The hollow is filled with a first material forming a substrate in which at least one housing is arranged. The housing is arranged so that at least one aesthetic element is housable therein. The substrate further includes a gripper deforming by thermal expansion to retain the aesthetic element in the housing. The gripper further includes at least one setting element. A method for setting an aesthetic element on a support includes taking a support provided with at least one hollow, taking at least one aesthetic element, filling the hollow with a first material, making a setting hole and a gripper in the first material, and setting the aesthetic element by placing it in the hole and by deforming the gripper so as to retain the aesthetic element.
