In one embodiment, each connecting earring back element includes a magnet or the body is made of a magnetic material such that the connectable earring back elements may be connected through magnetic forces. In some instances, a display panel may be included in an earring set to display the earrings, where the display panel may be decorative and may include magnets or be made of a magnetic material for affixing of the connecting earring back elements thereto.

A system for retaining an earring with in a gauge hole of an ear. The system is configured with a sleeve defining a resilient passageway. A post of a pierced earring is releasably secured within the resilient passageway and the sleeve is releasably secured with in the gauge hole of an ear. The system may be used to allow prior art ear gauges to retain pierced earrings within a gauge hole of an ear.

Disclosed is a connector suitable for use in jewelry, comprising a female component configured for reversible mating with a male component.

Security and tracking systems disclosed herein include a server coupled with a database, a computing device coupled with the database and including a display, and a wearable recording device (device) configured to record audio and video, the device having an identifier associated with the user through the database. One or more user interfaces are displayed on the display and include one or more inputs configured to associate the identifier with the user through the database. The wearable recording device may be an earring. Some security and tracking systems include a tracking device (tracker) having at least one sharp end, the tracker configured to be insertable into a hem or fold of a clothing item, the tracker having an identifier associated with the user through the database using inputs on one or more user interfaces displayed on the display, the tracker including a visual display of the identifier.

The invention is an earring (1) comprises a pointed pin (2) adapted to be reversibly inserted into a receiving housing provided with a means (10) for guiding the pin (2), the cylindrical housing also comprising at least one seal (15). The guide means is formed by a concavity (10) whose bottom (12) is open, the diameter (D) of the open base (11) of the concavity (10) being at least 30% greater than the outer diameter of the cylindrical housing, the depth (P) of the concavity (10) being equal to half the length (L) of the cylindrical housing. The pin (2) is provided with at least two circular grooves (16) suitable for temporarily receiving two annular seals (15) when the pin is inserted into the slot of the seals.

A holding member secures an object in position relative to an element having a bore. The object has a male part designed as a pointed rod, the free end of which is suitable for inserting in a reception housing provided in a female part of the holding member. The reception housing is provided, at its opening, with a conical member for guiding the male part into the reception housing. The holding member also includes a ring and seals inserted between the cylinder and a main body of the holding member.

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.
