Abstract
A jewelry article includes an elongated support and a multiplicity of ornaments strung along the support, at least one of which constitutes an adjustable self-stopping bead. Each self-stopping bead has a rigid shell with a pair of holes sized to slidably receive the support. A flexible resilient tube is positioned inside the shell in alignment with the holes that tube having a length that is as great as or slightly greater than the spacing of the holes, an outside diameter that is slightly larger than the diameter of the holes and in inside diameter that is slightly smaller than the maximum cross-sectional dimension of the support so that the tube resiliently engages the support to adjustably fix the position of the self-stopping bead along the support. A method of making the self-stopping bead is also disclosed.
