Abstract: A turning mechanism for a piece of jewelry, showing one of two opposing faces, includes a bale having a central opening and two opposite ends. At least one barbell-shaped pin has spheres at each end. The pin passes through at least one of the two opposite ends of the bale. One sphere projects into the central opening and secures the pin to the bale while the other sphere secures the piece of jewelry to the bale so that the piece of jewelry may be swiveled by a wearer to show another one of the two opposing faces. The faces may be “day” and “night”. The piece of jewelry may be a pendant on a necklace, an earring, a bracelet, or a ring. There may be a thickened portion of a trapezoidal shape at one of the two opposite ends of the bale to resist stresses and to prevent breakage of the pin.

Abstract: A jewelry clasp is provided with a male element and a female element. The female element has a chamber with a frame and an internal stop element that is integral with the frame. The chamber includes a pivot for a pivotally-mounted spring-biased latch element so that the latch element is not placed in the trajectory of the entry path of the male element into the entry port of the chamber, and the latch element is configured to abut the chamber frame such that, in every position, the latch element remains within the chamber frame and does not extend beyond the frame when the male element is engaging, engaged, disengaging or disengaged.
