A jewelry item has a closure that uses shape memory to provide two stable positions. For example, an earring has a setting and a pin, and the closure closes the pin over the ear. The closure consists of a leaf spring extending outwardly in a first loop part from a first location on the setting and looping back in a second loop part to a second location adjacent the first location on the setting. The loop parts each have shape memory and are set with different remembered shapes. The two different remembered shapes work against each other to flip the closure between two stable positions, a first position in which the closure connects to the pin to close the earring and a second position in which the closure is spaced away from the pin to open the earring. The design is particularly suitable for a huggie style earring.
A jewelry item, the jewelry item having two ends and a closure spanning a space between said two ends, the closure comprising a leaf spring extending outwardly in a first loop part from a first location on the first end and looping back in a second loop part to a second location adjacent the first location on the first end, the loop parts each having respectively different remembered shapes, said different remembered shapes configuring the closure to flip between two stable positions, a first position in which the closure connects to the second end to close the earring and a second position in which the closure is spaced away from the second end to open the jewelry item.
