An adjustable jewelry assembly comprises a releasable clamping device and an elongate flexible member, such as a necklace or bracelet chain, that is releasably secured to the clamping device. The elongate flexible member forms a loop portion at one side of the clamping device and a pair of legs at an opposite side of the clamping device. The clamping device includes a cap and an insert slidably mounted in the cap. The legs extend through openings in the cap and insert. A biasing member is located between the cap and insert for biasing the insert away from the cap. When the clamping device is at rest, the openings are misaligned and a shear force is applied to the legs, thereby securing the legs against slidable movement with respect to the clamping device. Pressing the cap and insert toward each other against the biasing force causes the openings to align and release the shear force so that the legs can slide with respect to the clamping device. In this manner, the size of the loop portion can be adjusted to accommodate the preferences of the jewelry wearer.
