Decorative piece produced by setting on amorphous metal

A decorative piece comprising:

• a support produced in a material which does not include plastic deformation and in which at least one hollow is provided, the hollow including side flanks made of the material which does not include plastic deformation,
• a first material within the hollow so that the side flanks are maintained in direct frictional contact with the first material to retain the first material,
• at least one setting hole formed within the first material,
• an aesthetic element positioned within the at least one setting hole and in direct contact with the first material,
• the at least one setting hole having a height that is greater than a height of the aesthetic element such that the aesthetic element is positioned entirely within the at least one setting hole,
• the first material being an at least partially amorphous alloy forming a substrate in which the at least one setting hole is provided,
• said substrate comprising in addition a catching mechanism that is made of the first material and that deforms in order to retain said aesthetic element in said at least one setting hole, and
• the catching mechanism being disposed at least at two opposing ends of the substrate that are in direct frictional contact with the side flanks of the hollow in the support.
