A jewelry closure mechanism (e.g., clasp) may include a locking receptacle and a locking pin that operate together to provide a closure mechanism for a piece of jewelry. The closure mechanism may or may not include a hinge. In some implementations, a locking pin may extend from the second arm and be inserted into a locking receptacle formed in a second arm to lock the two components together. The locking receptacle may include one or more wires (e.g., spring and/or precast) that extend transversely to the direction of the locking receptacle. The closure mechanism may be used as a general jewelry closure device and/or to couple segments of j ewelry together.

A jewel and/or jewellery article includes a frame, a flap able to move with respect to the frame, configured to admit a first configuration wherein the flap at least partially covers the frame and at least one ornamental element that it includes, and a second configuration wherein the flap at least partially uncovers the frame and the ornamental element, a drive mechanism configured to cause to slide on the frame, in a first sliding direction, the at least one flap between a first position in the first configuration of the article and a second position in the second configuration of the article, and an actuation mechanism configured to act on the drive mechanism when the actuation mechanism is urged in a second actuation direction different from the first sliding direction.

Jewelry that includes a topographical feature of a selected geographic location is made by obtaining topographic data for a geographic area around the selected location. The data is then used to create a topographic surface that is representative of the topography of the area and the 3D surface is adjusted for scale, viewpoint, and other features and merged with a template for a piece of jewelry. The resulting merged object is printed and the printed object is cast to produce a piece of jewelry that includes a topographic representation of the selected location.

A system and method for multi-orientation jewelry. The system includes a pendant body which has a perimeter. Along that perimeter are at least two holes. These holes are in fluid communication with the other holes. The system also includes a coupler which can couple with at least two holes. The orientation of the pendant can be modified by selecting different holes with which to couple.

A pendant for a necklace has a body with an aperture, and a hole extending into the body from the aperture. The hole terminates at a closed bottom in the body. A body coupling is adjacent the aperture. A lid can be attached to and detached from the body. The lid also can be mounted to the necklace to support the body therefrom. The lid has a lid coupling to couple to the body coupling to close the aperture. The lid coupling can be uncoupled from the body coupling to provide access to the hole. A container is removably mounted in the body. The container has a retained position where the container is in the hole in the body when the lid is mounted to the body. The container also has a released position with the lid detached such that the container is at least partially exposed from the body.

An ornament clasp and an ornament that can be easily attached and detached. The ornament clasp includes a holder (10) on a fixed side having a holding portion (20) where a personal ornament main body (2) is held via an opening (21), a closing member (12) on a movable side rotatably attached to the holder via a pivotal attaching portion (28) and locking form inside the opening to cause a closed state, a soft member attached to the closing member at least on a side of gripping the personal ornament main body, and a spring (13) attached in a repulsive state between the holder and the closing member and pressing the closing member in a direction of closing the opening. A grip space S where the personal ornament main body is gripped in a repulsive direction of the spring is provided between the soft member and the holding portion.

A lock mechanism includes a chain component and a lock connector component. The chain component has a head portion at one end. The lock connector component has a button portion, an accommodating space, and an opening disposed on a side adjacent to the button portion, wherein the opening space connects to the accommodating space. When the button portion is operated in a pressed state, the button portion is configured to block the head portion from entering or exiting the accommodating space via the opening. When the button portion is operated in a depressed state, the button portion is configured to allow the head portion to enter or exit the accommodating space via the opening.

The present invention provides a gemstone comprising a girdle dividing the gemstone into a pavilion and a crown having a table surface; a tier of facets cut into the pavilion at a position immediately below the girdle; and a continuous groove. The groove facilitates mounting to a collet having a mounting rim. The continuous groove is located in the tier of the facets cut into the pavilion. The placement of the tier of facets and continuous groove does not obstruct light return.

A convertible pendant is disclosed in which a link connects to a first ornament. The pendant may have a first configuration in which a second ornament is housed within the first ornament and a second configuration in which the second ornament is deployed from the first ornament. In either configuration, the second ornament may be connected to the first ornament so that the second ornament is not easily lost. In a third configuration, the first and second ornaments may be detached from the link. The different configurations provide a pendant that may be adapted to suit different occasions.

An articulated cross pendant, such as may be worn on a necklace around the neck of a user, is disclosed. The pendant has an upright bar crossed by a horizontal bar. The horizontal bar has right and left arms extending to the left and to the right of the upright bar, respectively. The upright bar may have an upper portion extending upward and a lower portion extending downward from the horizontal bar. The lower portion may be elongated such that it is longer than the upper portion and longer than each of the right and left arms of the horizontal bar. The top end of the upper portion may be looped, and the lower portion is fully articulated to prevent the ends of the upright bar, worn on a necklace, from poking or piercing the skin of a user when the user bows the head downward toward the chest.
