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.

An item of jewelry has a decorative element that is provided with a shaft which interfaces with an annular element such as a ring. A portion of the ring has, within its thickness in the radial direction, a radial notch, followed by a circumferential notch, thus forming approximately a L-shaped notch. An elastically deformable element is accommodated on the inner face of the ring, making it possible to lock the decorative element in position on the annular segment after introducing the shaft as far as the bottom of the L-shaped notch.

A jewelry setting for securely holding a stone, such as a gem or a diamond, where the stone has at least one peripheral tip. The setting includes a base and a plurality of prongs. The prongs have an inclined portion extending from the base outwardly at an angle, and a vertical portion projecting vertically from the inclined portion. A cavity in one or more of the prongs positioned to receive the peripheral tip of the stone is stamped in the vertical portion of the prongs. The cavity has a plurality of faceted walls adapted such that when the peripheral tip of the stone is received in the cavity, the facets of the cavity engage the facets of the peripheral tip.

A jewelry ring assembly includes a base ring having an annular channel on its outer surface and a retained ring disposed in that channel to be freely rotatable about the base ring and capable of wobbling in the channel. The base ring is a single piece of metal and its retaining channel is smoothly concave in width between raised annular edges. The base ring is formed from a cylindrical blank initially having a constant outside diameter across its width, which diameter is smaller than the retained ring inside diameter. The method of fabricating the ring assembly begins with flaring one edge radially outward to a final diameter larger than the retained ring inside diameter. The retained ring is moved over the unflared edge, after which that edge is also flared to the final diameter. Enlarging the annular edges in separate steps permits the base ring to be formed from a single piece of metal while presenting a retaining channel having a smooth concave width.

A silver filled gold jewelry wire item includes an inner precious metal core, such as silver, and an outer gold layer. The outer gold layer has a predetermined thickness of from about 0.0001 inch to about 0.002 inch, preferably no more than 0.001 inch thick, which is much thinner than durable hollow wires of at least 0.004 inch in thickness or greater. A forming process draws a gold sheet strip into an open channel shaped member into which a solid silver core is placed at ambient temperatures. The open channel shaped member is closed by further rollers at ambient temperatures and welding of a seam when closed about the solid core. The resultant solid tubular gold jewelry wire item resists damage from diamond cutting knives, and can be used to create jewelry rope chains, earrings and bangles.

A prong setting for a ring or other jewelry item is provided. The prong setting is mounted along the jewelry item and includes one or more first prong elements and one or more facing second prong elements for defining an opening therebetween in which a jewelry stone is received. Preferably, each prong element includes a wire or lip portion for selectively engaging the jewelry stone. The wire portion is specially sized and shaped to enhance the strength of the setting in holding the stone therewith. In one embodiment, the prong elements are movable with respect to one another in order to be able to selectively adjust the distance between the prong elements, and thus the size of the opening. As a result, the prong setting can accommodate jewelry stones of varying size.

Jewelry pieces formed entirely or partially of a shape memory alloy provided with a pre-determined memory shape, where the shape memory characteristic and/or the superelastic characteristic of the alloy is used either in the construction of the piece or to facilitate repair of damaged pieces, since plastically deformed alloy shapes can be corrected by raising the alloy above the phase transition temperature, whereupon the piece resumes it memory shape.
