Abstract: A jewelry ornamentation device that is selectively securable with respect to a basically conventional substrate jewelry such as a necklace, bracelet, ankle bracelet or the like. The detachable jewelry device includes a base plate and a clamping arm pivotally secured to one another and a clasping device for selectively securing the to one another. A compression member of flexibly resilient material is mounted between the movable members and is retained in position by a positioning device preferably in the form of two posts extending upwardly in the holes defined in the compression member to facilitate securement in position on the clamping surface of the base plate member. With the substrate jewelry extending positioned adjacent to the compression member, the ornamentation securable to the clamping arm can be fixedly secured with respect to the substrate jewelry at any chosen location by securement of the clasping apparatus.
