Abstract: A method is provided for closing a jewelry item that has a first side including a first and second end, the first end having a stem and locking notch. A second side of the jewelry includes a third and fourth end, the second end of the first side is connected to the fourth end of the second side. The jewelry has a closure having a collar rotatably connected to a rotatable connection element, where the collar is connected to the third end and located between the third end and the rotatable connection element. The method includes pressing the first end of the first side towards the third end of the second side. In an unlocked configuration, the stem with the locking notch of the first side is inserted within a locking cavity of the rotatable connection element. In a locking configuration the rotatable connection element is rotated to engage the locking notch of the stem, preventing removal of the stem from the rotatable connection element.

Abstract: 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.

Abstract: A jewelry item has a first side including a first and second end with a stem and locking notch and a second side including a third and fourth end with a mounting stem and ball joint. The second end of the first side is connected to the fourth end of the second side. A closure has a collar rotatably connected to a rotatable connection element. The collar is connected to the third end and located between the third end and the rotatable connection element. In an open configuration, the stem with the locking notch of the first side can be inserted within a locking cavity of the rotatable connection element. In a closed configuration, the rotatable connection element is configured to be rotated to engage the locking notch of the stem, preventing removal of the stem from the rotatable connection element.

Abstract: A handheld digital measuring device, method and kit therefore are provided. The device includes first and second elongated, substantially flat blade members having proximal and distal ends. At a proximal end thereof, the blade members are fixed to and extend from a housing. The first and second blade members are movable relative to one another in an opposing manner to provide a defined and measurable distance between the distal ends of the first second blade members. Optionally, the device may have a photosensor for sensing a dimension of the distance between the distal ends of the blade members and a microcomputer responsive to photosensor signals for transmitting the distance to a display device. The device may also comprise a spring-loaded pneumatic mechanism for urging the blade members apart. The device is preferably handheld and includes buttons or a keypad for controlling operation thereof.
