The jewelry item comprises an elastic element, which extends along an extension direction of the item through the entire length of the item, and a plurality of ornamental elements, which are threaded one after the other on the elastic element so as to be slidable relative to the elastic element and are non-releasably connected in twos to one another. Each ornamental element comprises a hollow body having a pair of longitudinally opposite first faces, namely a right-hand face and a left-hand face, respectively, and a pair of radially opposite second faces, namely an inner face and an outer face, respectively. The right-hand face of each ornamental element has a through opening communicating with an inner cavity of the ornamental element.

A flexible jewelry cable includes a plurality of helical links. Each link has a body that extends helically about a central axis of the link. Each link includes a protrusion extending from an inner surface of the body at or near ends of the body. Each protrusion defines a through hole that is coaxially aligned with the body. The body defines a female recess on the inner surface of the body, each recess corresponding to one protrusion. The recesses are at or near the ends of the body. One recess of a first one of the links is configured to receive one protrusion of a second one of the links and align the hole of the received protrusion with the hole of one protrusion of the first link. The cable includes a string extending through the aligned holes of the protrusions of the links.

A flexible luxury strap is provided having a plurality of beads attached (or linked) to each other to form a substantially rectangular array of alternating first and second rows. The array has a length and a width. The first row has a number of substantially identical beads greater than the number of beads in the second row. The second row has a bead of an elongate shape whose length defines the width of the array. In some instances, the bead of an elongate shape may be formed by adhering a plurality of smaller beads together. Substantially all or all of the beads may be crystals.

A rigidifiable flexible device includes a flexible member having flexibility, a plurality of movable members arranged in a line on a path between one end and the other end of the flexible member along a longitudinal direction of the flexible member, the movable members being movable on the path, a stopper provided at the one end of the flexible member and configured to prevent the movable members from being removed from the path beyond the one end of the flexible member, and a blocking member configured to prevent the movable members from being removed from the path beyond the other end of the flexible member. The length of a portion of the path between the blocking member and the stopper is adjustable so that the movable members are brought into close contact with each other on the path to form an integrated support body.

A jewelry item comprises an elastic element extending over the entire length of the item, a plurality of decorative elements threaded one after the other on the elastic element so as to be slidable with respect thereto, and a plurality of connection elements which are each threaded on the elastic element between a pair of adjacent decorative elements and connect the decorative elements to each other, whereby the adjacent decorative elements are displaceable with respect to each other, sliding on the connection element, between a position of minimum relative distance and a position of maximum relative distance. Each connection element is connected to a first decorative element of the pair of adjacent decorative elements by a first bayonet-type engaging device and to a second decorative element of the pair of adjacent decorative elements by a second bayonet-type engaging device.

The jewellery item comprises an elastic element, which extends along an extension direction of the item through the entire length of the item, and a plurality of ornamental elements, which are threaded one after the other on the elastic element so as to be slidable relative to the elastic element and are non-releasably connected in twos to one another. Each ornamental element comprises a hollow body having a pair of longitudinally opposite first faces, namely a right-hand face and a left-hand face, respectively, and a pair of radially opposite second faces, namely an inner face and an outer face, respectively. The right-hand face of each ornamental element has a through opening communicating with an inner cavity of the ornamental element.

A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. One or more beads may be assembled to a linked item formed with Brunnian links. The beads include tapered sides to provide a curved interface that corresponds with the shape of a completed linked item.

A jewelry item comprises an elastic element extending over the entire length of the item, a plurality of decorative elements threaded one after the other on the elastic element so as to be slidable with respect thereto, and a plurality of connection elements which are each threaded on the elastic element between a pair of adjacent decorative elements and connect the decorative elements to each other, whereby the adjacent decorative elements are displaceable with respect to each other, sliding on the connection element, between a position of minimum relative distance and a position of maximum relative distance. Each connection element is connected to a first decorative element of the pair of adjacent decorative elements by a first bayonet-type engaging device and to a second decorative element of the pair of adjacent decorative elements by a second bayonet-type engaging device.

An article of jewelry or costume jewelry having at least one elastic or flexible support element and a plurality of ornamental elements fitted in succession on the elastic or flexible support element and coupled two by two along a development direction of the article of jewelry or costume jewelry is provided. Each ornamental element has a first coupling face for coupling to a subsequent contiguous ornamental element, the first coupling face having a raised formation, and an opposite second coupling face for coupling to a previous contiguous ornamental element, the second coupling face having a recess complementary in shape to the raised formation of the previous contiguous ornamental element. Two contiguous ornamental elements are coupled together by accommodating the raised formation of a first element of the two contiguous ornamental elements within the recess of a second element of the two contiguous ornamental elements, with at least one shock-absorbing spacer element arranged therebetween.

A jewelry item is provided to include a ring-shaped spring and a ring-shaped chain. The ring-shaped chain has a plurality of chain links, each of which is slidably attached to the ring-shaped spring. Each chain link has a plate with a first surface facing the spring and a second surface opposite to the first surface. Each chain link further has a seat and a hook opposite to each other. The hook is inserted into a seat of a subsequent chain link so as to lock the chain links to each other while allowing the chain links to reversibly slide from a compressed position to an expanded position with respect to each other.
