A center-cast tool for casting a non-uniform object is provided. The center-cast tool has a body having a casting bay recessed into the top side of the body. A base forms the bottom of the casting bay. First and second apertures extend through the base and the bottom side. The second aperture intersects the first aperture in perpendicular orientation to the first aperture to form an aperture intersection. The aperture intersection forms four opposing right angles on the base at the center of the bay. The distance between adjacent right angles in the base is equal to the length of each side of the bezel of a jewelry article into which the finish machined irregular object will be set. In another embodiment, a first release hole extends through the base and the bottom side on a first side of the aperture intersection.

A bracelet made of synthetic material for watches or jewellery includes at least one strand formed of an extruded or injection moulded band, wherein at least one strand has a roughness Rp less than or equal to 3 μm and preferably less than or equal to 2 μm.

A method for manufacturing a jewel for a timepiece, the jewel including, for example, poly-ruby of the Al2O3Cr type or Zirconia of the ZrO2 type, including first producing a precursor and a then pressing the precursor in order to form a body, the pressing being carried out using a pressing device provided with an upper die and a lower die defining a pressing space wherein the precursor is disposed, the upper die including a concave portion of oblong shape, the device having a wire at least partially traversing the lower die to open into the pressing space, the lower die being able to slide around the wire, the pressing being carried out by bringing the lower die and the upper die closer together to form a body including an upper face provided with a dome and a lower face provided with a hole extending at least partially into the dome.

The present innovation is an innovative process for the manufacturing of jewelry or jewels with silver or gold adornments, such as bracelets, necklaces, earrings, pendants, among other artifacts, from the re-utilization of strings of tennis rackets disposed of by players, forming a polymer mass that is treated to generate the pieces, such as beads, which make up the final artifact.

A Brunnian link is a link formed from a closed loop doubled over itself to capture another closed loop to form a chain. Elastic bands can be utilized to form such links in a desired manner. The example device provides a means of holding elastic bands in place to enable the creation of an item formed of Brunnian links.

Jewelry bezel settings have a band defining an aperture shaped to receive a stone. The band has a flange defining an upper opening and a pavilion-facing interior surface defining a lower opening. The flange extends radially inward a pre-selected distance to sit on a top edge of a girdle of the stone, and the pavilion-facing interior surface is angled to seat against facets of the stone. A channel is formed in and extends around an interior perimeter of the band between the flange and the pavilion-facing interior surface, and a cured material fills the channel and defines a plurality of pavilion facet-mating surfaces. The cured material defines a layer having a preselected color selected to enhance a brilliance of the stone.

Kits and methods of play for creating decorative objects are disclosed. In a preferred embodiment, a kit comprises a plurality of rubber sticks, each stick with a continuous internal pattern that extends down the entire length of a longitudinal axis of the stick; a coring device, wherein the coring device includes a core cutter that is designed to cut holes through the plurality of rubber sticks; a cutting device designed to cut segments from the plurality of rubber sticks; and, a plurality of retainers designed to couple a plurality of segments together.

An article of jewelry comprising; a frame; and a decorative element secured within the frame, wherein two-dimensional array of optical phase shifting structures is embedded in the decorative element; wherein the two-dimensional array of optical phase shifting structures project an image when illuminated with a light source.

A clip having superimposable parts for securing, between the parts, thin pliable materials, at any locations on the material, adjacent the material edges or at any position between opposing material edges.
