Jewelry with slidable, add-on gems

A jewelry item comprising an elongated supporting member, means on said supporting member for supporting it from a wearer, and at least one gem and gem mount mounted on said supporting member, said gem mount including a mounting base and prong means for supporting the gem and a split sleeve, said split sleeve having a longitudinal slit in a wall portion opposed to the mounting base enabling lateral assembly of the gem mount onto the supporting member when the split sleeve is spread apart with the split sleeve securing the gem mount on the supporting member when closed, said slit being defined by abutting end edges of the wall portion, said wall portion being constructed of ductile metal, said supporting member being an elongated rigid bar of polygonal cross-sectional configuration and having a constant cross-sectional area over a major portion of its length, said sleeve having an internal configuration corresponding to and closely conforming to the bar to prevent rotation of the gem and gem mount about the longitudinal axis of the bar while enabling sliding adjustment along the length of the bar, said supporting means including chain segments having a smaller cross-sectional area than the bar with each chain segment having one end fixedly secured to an end of the bar, the end portions of the bar tapering to provide a gradual and smooth transition from the bar to the chain segments with the chain segments forming an axial continuation of the tapered end portions, and fastener means detachably connecting the other ends of the chain segments to mount the item of jewelry in encircling relation to a portion of the anatomy of a wearer, said bar being curved with the convex surface having the gem projecting therefrom, the inner concave surface of the bar being provided with a projecting limit stop adjacent each tapered end portion of the bar to prevent the gem mount from sliding off the end of the bar onto the chain segments.
