A jewelry item has a ring part pivotally attached to a closure at one end, the closure comprising a ring continuation arm pivotally attached to the ring part, and a bias arm which in turn has a spring part and a lever pivotally attached to each other, the bias arm being rigidly attached to the ring part, so that as the ring part is opened, the lever rotates inwardly, pulling the pivoted end of the spring part, the spring part having a natural shape of smaller circumference than the ring itself so that once a certain extent is reached, the spring part pulls the lever to allow the spring part to attain its smaller diameter and thus establishes a stable open position. On closure of the ring part, the lever pushes the spring part outwardly towards the ring continuation arm to establish a second stable position to close the earring.

Two plates, corresponding to the diameter of a length of riveting material being used, act as gauges and are placed separately on the top and bottom of at least one components to be made into a jewelry item. The length of material, such as a wire or tubing, is passed through holes in all the components, and the holes of the plates. This allows the jewelry maker to cut the length of material flush with the exposed surface of the plate on the top of the stack. This automatically measures the optimal length of material needed to span the combined thickness of all the components to be riveted together, while providing the desired length exposed at the top and bottom of the stacked pieces, to fashion a properly formed and secure flattened rivet head on each end of the length of material.

Light, precious gold-titanium based alloy containing, by mass, at least 750% of gold, characterized in that said alloy has the following composition formula:

Ti.sub.aAu.sub.bM.sub.cT.sub.d

where a, b, c, d are atomic proportions such that:

a+b+c+d=1,

0.45≦a≦0.55; 0.41≦b≦0.495; 0.025≦c≦0.13; 0.001≦d≦0.025,

where M represents one or more elements taken from among a first group including Nb, V, Pd, Pt, Fe,
and where T represents a maximum of two elements taken from among a second group including Nb, V, Pd, Pt, Fe, Mo, Ta, W, Co, Ni, Ru, Rh, Ir, Cr, Mn, Cu, Zn, Ag, Al, B, Si, Ge, Sn, Sb, In, with the exception of said metals M comprised in said alloy.

Component for timepiece or for jewellery made from such a light, precious gold-titanium based alloy.

A disclosed bead bracelet loom for making a beaded item includes a clip disposed at one end of a track and configured to hold a portion of a cord. A holder is disposed on the track and spaced apart from the clip. The holder includes a key portion that engages a portion of the track to maintain a position of the holder spaced apart from the clip. The holder including a spring portion that holds a clip configured to hold an end of the cord and maintain a desired tension on the cord member between the clip and the holder.

The present invention relates generally to a coated jewelry article or a coated component of a jewelry article, comprising a jewelry article or a component of a jewelry article, a first metallic coating, and a second metallic coating.

A handheld loop former for beading wire is provided. The loop former comprises a cutting lever, a slotted forming platform, a forming lever, and two scissors links. The cutting lever has a combination shear blade/forming die at its distal end. The slotted forming platform has a medially located slot, a shearing ledger, and a forming stanchion. The forming lever has a second forming die at its distal end. The cutting lever, forming platform at the medially located slot, and forming lever are journaled together with a pivot pin. Each of the forming lever and the cutting lever is journaled to one of the scissors links. Both scissors links are journaled to the forming platform. The sheer blade/forming die passes closely to the shearing ledger and with the second forming die envelops the forming stanchion when the forming lever and cutting lever are urged together. The forming platform is drawn proximally.

A method for depositing a rare material in a thin layer at the surface of an horological or jewellery external part includes providing a rough part of rare material, shaping the rough part of rare material so that it is adapted to be used as a target part for a PVD method, depositing material of the target part at the surface of a substrate consisting of an horological or jewellery eternal part by a PVD method so as to cover the external part.
