A piece of jewellery has elongated longitudinal frame parts (1, 3) arranged in pairs next to each other at a constant distance from each other in the longitudinal direction and mutually linked by transverse strips (5), thus forming a rigid guiding frame. Each longitudinal frame part comprises an elongated base body (9) designed in particular as a tube with a ring-shaped, closed tubular wall, from which projects a guiding rib (11) that extends in the longitudinal direction up to the other longitudinal frame part. Jewellery elements (7) are freely movable on the guiding ribs. The circumferential profile of the base body (9) joins the guiding ribs (11) on both sides without undercuts. This design makes it possible to obtain mechanically stable guidance of the movable jewellery elements (7). In particular, jamming of the jewellery elements (7) due to dirt deposits in the area of the guiding ribs is avoided. |
