A method of fabrication of a wristband of a watch or piece of jewelry, including: providing a first synthetic material; providing an extrusion line with a die plate for making an extrudate from the first material; providing one or more additional materials distinguished in their properties from the first material; providing a die plate including a first zone defining a profile allowing for fabrication of an extrudate having a hollow tubular profile at least at one of its ends in which the extrudate has a width corresponding to the length of one or two strands of the wristband; the die plate further includes a second zone allowing defining of particular profiles selected from among a flat profile, a curved profile, or a profile with projecting zones.

The invention relates to watch straps made of felt material. The method includes cutting out the strap from the felt material with a density of up to 0.5 g/cm.sup.3; forming the ends of the strap to be fastened to the watch body by adjusting the shape of the strap ends to the shape of a specific watch body and/or to strap fastening elements; impregnating the shaped ends of the strap with polymeric glue, preferably with liquid cyanoacrylate; precisely adjusting the fully dried and processed strap ends to the watch body or strap fastening elements; drilling the transversal apertures in the strap ends for inserting the watch pins to fasten the strap to the watch body. The watch strap thus obtained is eco-friendly, recyclable, non-allergenic and can be securely fastened to the watch body.

Disclosed is a method for manufacturing a casing element made of ceramic, for the fields of watchmaking or jewelry making, which enables a casing element to be obtained that is substantially homogeneous in terms of its structure and mechanical properties and that has variations of hue and/or color that are both original and unique on its surface. The manufacturing method includes, in particular, a machining step intended to make different layers, of different respective natures, visible on the surface of the casing element.

Compositions for enhancing the luster and/or brilliance of jewelry and/or gem stones comprising a non-aqueous carrier and optionally additives and/or fragrances, and methods for making and using same.

Tooling strips and tools for using tooling strips.

A hand jewelry such as a ring or a bracelet has been presented herein. The ring or the bracelet may be obtained by performing one or more molding processes. The jewelry may include at least inner and outer components that are formed together (i.e., single molded) into a single unit. The inner component may include an elevated portion that is a circular step or portion along an inner surface of the inner component. A width of the elevated portion is less than a width of the inner surface of the inner component. The elevated portion may include one or more grooves molded therein. The jewelry may also include one or more outer caps for covering at least a portion of the outer component of the jewelry from outside.

The present invention relates to a piece, in particular for jewellery or timepieces, made of a material comprising a synthetic matrix (2) loaded with particles (3) of a precious or semi-precious stone, said particles (3) having a particle size d90 comprised between 50 m and 2 mm, preferably between 100 m and 1 mm, and, more preferably between 150 m and 500 m.

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.

A piece of jewellery made of a natural elastomer composite material, wherein the natural elastomer composite material includes a natural elastomer matrix wherein between 0% and 6% cellulose fibres, between 0 and 5% anti-odour agents, and between 0 and 30% silica are dispersed.

Provided is a method for manufacturing a synthetic gemstone, which manufactures a synthetic gemstone from a body tissue separated from a person or an animal, the method including: extracting a biological material from the body tissue; preparing a mixed material by mixing the biological material with a gemstone material; and growing a synthetic gemstone on a crystal seed as a single crystal by melting the mixed material.
