This disclosure enables various lines, earrings with such lines, and methods of manufacture and use thereof. For example, some of these lines may extend (e.g., span) between a pair of earrings worn on a pair of cars of a wearer. This form of extension may or may not be arcuate, parabolic, hyperbolic, or gravitational.

A modular element for making jewellery items, trinkets, and the like, having a convex outer surface and a through hole arranged at the top of the outer surface, where a wire, chain, or support for making the jewellery item, trinket, and the like can be inserted through the through hole, a main axis of symmetry passing through the hole, including a concave inner surface intended to at least partially accommodate the outer surface of a second element adjacent to the first one, where the outer surface can be inscribed on a rotation surface whose generatrix is an arc of a conic section and whose axis of rotation coincides with the main axis of symmetry. Embodiments also include a jewelry item.

The present invention concerns a toy bead (10, 100) comprising: two conjugated parts (11, 12; 110, 120), each part comprising a proximal end and a distal end; proximal ends of said conjugated parts comprising conjugated screwing means (11a, 12a; 110a, 120a) adapted to screw conjugated parts to each other in order to build the bead; distal ends of said conjugated parts comprising plugging means (17, 18; 170, 180), either male or female, adapted to plug said parts respectively to parts of other similar toy beads comprising corresponding plugging means; each conjugated part further comprising an internal canal (15, 16; 150, 160) extending from its proximal end to its distal end and opening to each end, the internal canal of one part being collinear to the internal canal of the its conjugated part when the conjugated parts are screwed to each other, so that a yarn can be threaded successively into internal canals of said conjugated parts.

Present disclosure is directed to inventive methods and systems for providing electrical power to one or more charms operatively connected to an electrically powered jewelry. Accordingly, various embodiments are directed to a bracelet having at least a first and a second powered rail, the first rail having an electric potential lower than the second the rail such that a potential difference exists between the rails. In an embodiment, the first and second rails exists form an open circuit that may be closed by attaching one or more charms.
