摘要

The ring (10) is set with a precious stone (23), such as a diamond, in such a way that the stone can turn around a longitudinal axis perpendicular to its face. It consists of a cup (13) which is fixed to the exterior surface of the circular ring (11) by claws (12a, 12b). A flat disc (16) almost completely fills the opening of the cup and a decorative plate, preferably of semi-precious stone, is fixed to one face (17) of this. On the other face (19) a perpendicular axle (20) is fixed and a bent arm (22) is fixed to this. The precious stone is held by the free extremity of the arm.
