A jewelry item has a ring part pivotally attached to a closure at one end, the closure comprising a ring continuation arm pivotally attached to the ring part, and a bias arm which in turn has a spring part and a lever pivotally attached to each other, the bias arm being rigidly attached to the ring part, so that as the ring part is opened, the lever rotates inwardly, pulling the pivoted end of the spring part, the spring part having a natural shape of smaller circumference than the ring itself so that once a certain extent is reached, the spring part pulls the lever to allow the spring part to attain its smaller diameter and thus establishes a stable open position. On closure of the ring part, the lever pushes the spring part outwardly towards the ring continuation arm to establish a second stable position to close the earring.
A jewelry item, the jewelry item having a ring part pivotally attached to a closure at one end, the closure spanning the continuity of the ring from an end of the ring part and comprising a ring continuation arm extending in continuity of the ring and pivotally attached to an end of the ring part at a pivoted connection, the closure further comprising a bias arm extending along with the ring continuation arm along said ring continuity, the bias arm comprising a spring part and a lever part pivotally attached to each other, a connection between said lever part and the ring part being rigid, so that as the ring part is opened, said lever part is configured to rotate inwardly towards an interior of said item, pulling the pivoted end of said spring part, the spring part having a natural shape of smaller circumference than said ring part so that once a certain extent is reached, the spring part pulls the lever part towards the spring part in order to allow the spring part to attain its smaller diameter and thus establish a stable open position, the lever further on closure of the ring part, being configured to push the spring part outwardly towards the ring continuation arm to establish a second stable position to close the earring.
A jewelry item comprising a ring part and a closure, the closure being continuous with the ring part and connecting to said ring part at a first end, the closure comprising a continuation of said ring part and a spring arm pivoted to said continuation at a first location thereon and further pivoted to said ring part at a second location, said continuation having a pivoted hinge located at said first end, said first end being between said first location and said second location, thereby providing said closure with a first open stable position and a second closed stable position and a snapping motion between said first and second stable positions.
