An earring includes a pointed pin adapted to be reversibly inserted into a receiving housing provided with a means for guiding the pin, the receiving housing also including at least one seal. The guide means is formed by a concavity whose bottom is open, a diameter of the open base of the concavity being at least 30% greater than an outer diameter of the receiving housing, a depth of the concavity being equal to half a length of the receiving housing. The pin is provided with at least two circular grooves suitable for temporarily receiving two annular seals when the pin is inserted into the slot of the two annular seals.

The present invention provides tools and a method for securely affixing flat padded earring posts onto cured polymer clay earrings. The tools include thickness guides, a disk-cutting tool, a dome-forming tool, and an alignment tool, enabling consistent and professional jewelry creation. The method eliminates the challenges associated with traditional adhesives, providing a more durable and polished finish suitable for jewelry crafting in various contexts.

In an illustrative embodiment, a reconfigurable jewelry piece such as an earring comprises hinged, articulating segments. Adjacent segments can be opened about a hinge, and when fully open the jewelry piece appears to have multiple geometric shapes attached to each other with swinging movement. The adjacent segments can also be closed about the hinge, in which case a closed segment fits around (circumscribes) the adjacent, smaller segment, making them appear unitary.

A jewelry item is provided having a first side, having a first and second end, the first end having a stem and locking notch. A second side includes a third and fourth end, the second end of the first side is connected to the fourth end of the second side. A rotating closure has a collar, rotatably connected to a rotatable connection element. The collar is connected to the third end of the second side and located between the third end and the rotatable connection element. The first end of the first side is configured to be movable towards the third end of the second side, such that in an unlocked configuration, the stem with the locking notch is configured to be inserted into the first side within a locking cavity of the rotatable connection element. In a locking configuration, the rotatable connection element is configured to rotate to engage the locking notch of the stem, preventing removal of the stem from the rotatable connection element.

An improved security clutch for a jewelry post with a circumferential groove includes a housing with a post receiving aperture extending therethrough and a port through a washer. The housing is provided with a top shell and a bottom shell. A back cup is secured to the top shell via a boss on the top shell and about an aperture of the back cup, preferably by riveting to provide an improved security clutch.

The invention relates to a backing for an earring, and to an earring with a backing. The backing is particularly suitable for a stud earring but is not limited to those applications and can also be used for a drop earring or hook earring if desired. The backing has a hole which is sized to accommodate a post of the earring and to be a frictional fit upon the post, the backing having a substantially planar surface which lies against the user's ear lobe in use, the hole extending in a direction which is substantially aligned with the substantially planar surface. The earring has a post with a first portion, a second portion and a bend between the first portion and the second portion. The backing is designed to fit to the second portion.

An earring back for secure but easily releasable engagement with an earring post or extension is provided. In an embodiment, the earring back includes an outer casing and an internal, compressible material such as silicone. The earring back further defines a center opening for receiving and engaging with an earring post or extension. In an embodiment, the outer casing comprises two pieces. A first piece is a back piece with an enclosed back end, an open opposite end providing access to an inner cavity, and a lip extending laterally from the open end. The second piece is a front piece having a radius larger than the radius of the lip of the back piece and defining the center opening. In an embodiment, a circumferential portion of the casing front piece is folded over and around a lip of the compressible material and the casing back piece lip and compressed.

An item of jewelry having a plurality of interchangeable decorative elements, the jewelry comprising an elastically deformable holding element and the decorative elements comprises a retaining bolt that is protruding from a core of the decorative element and which comprises a head at its end and comprises a constriction between the core and the head, wherein sections of the holding element project into the constrictions.

An ornamental fixing apparatus for a pin-type earring according to the present invention may include the ornamental fixing apparatus to which one end of an earring pin is inserted or fixed, a main body made of an elastic material and having a long hole into which one end of the earring pin is inserted, and at least one elastic reinforcement member provided in the main body or bonded to the main body and provided in a longitudinal direction of the long hole, in which the elastic reinforcement member is provided as a plate-shaped member extending in a direction intersecting the longitudinal direction of the long hole and delays or prevents a decrease in frictional force or compressing force applied to a contact surface between the long hole and the earring pin.

A front-insert, threadless earring system is disclosed. The system includes a decorative front element having a rearwardly extending tubular post with a hollow interior channel, and a flat-back element configured to rest against the rear surface of a wearer's earlobe. The flat-back element carries a forwardly projecting solid engagement pin sized to enter the hollow interior channel of the tubular post. When the decorative front element is inserted from the front of the earlobe and the flat-back element is advanced from the rear, the engagement pin forms a threadless interference-fit with the tubular post to secure the earring in place. The system provides a low-profile, comfortable rear backing, reduces mechanical complexity, eliminates threads and clasps, and enables intuitive, tool-free attachment and removal. The arrangement improves hygiene, comfort, and stability during continuous wear.
