A metallic mesh material used to form a portion of a band or securing strap for a wearable electronic device. The band may include a magnetic tab for securing a wearable device to the wrist of a user. The tab may include one or magnetic elements that are configured to engage a surface of the mesh to secure the wearable device to the wrist of a user.

Rings disclosed herein include a toroid formed of an expandable polymer, the expandable polymer having an elastic modulus of no greater than 5 gigapascals (GPa), the expandable polymer forming at least 80 weight percent of the toroid, the toroid sized to fit snugly over a digit of a user. In implementations a plurality of precious material particles are disposed within the expandable polymer, wherein the precious material particles include one or more of gold particles, non-ionic silver particles, copper particles, platinum particles, and crushed pearl particles. In implementations a plurality of grooves are formed on an inner surface of the ring and extend from proximate a top of the ring to proximate a bottom of the ring. In implementations no portion of the ring has an elastic modulus greater than 5 GPa.

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.

A composite material having a grainy appearance, this composite material including a metal matrix which represents, in terms of volume fraction, between 50 and 95% of the grainy composite material, the ceramic particles having a diameter that lies in the range 0.1 to 2 mm and which represent, in terms of volume fraction, between 50 and 5% of the composite material are dispersed in the metal matrix and form the remainder of this grainy composite material. A method for manufacturing a grainy synthetic material.

The present invention is an ergonomic silicone wedding ring comprising of 3 bands which are designed not to separate easily and are thinner, more ergonomic and comfortable than prior silicone tri-band rings.

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.

The method for manufacturing a ceramic component, in particular a ceramic component containing zirconia and/or alumina, for a timepiece or a jewelry piece, is characterised in that it includes a step (E3) of depositing at least one additional element or compound on a ceramic powder, optionally bound, by atomic layer deposition (ALD).

A process for manufacturing a ceramic powder with binder includes at least one additional element or compound, the ceramic powder with binder being in particular based on zirconia and/or alumina and/or strontium aluminate, wherein the process includes a step (E3) of depositing at least one additional element or compound on a ceramic powder with binder by a physical vapour deposition (PVD) and/or by a chemical vapour deposition (CVD) and/or by an atomic layer deposition (ALD).

A method for manufacturing a bracelet made of synthetic material for watches or jewellery including at least one strand, the method including a step of making, by moulding or extrusion, a band of synthetic material intended to form at least one strand, the method being wherein it then includes a step of chemical mechanical polishing the band. 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 m and preferably less than or equal to 2 m.

A jewelry charm includes a pair of identical main body sections, each having an inside facing surface, an outside facing surface, a centrally located cylindrical protrusion that is positioned along the inside facing surfaces, a centrally located cylindrical indentation that is positioned along the inside facing surfaces, an elongated indentation that encircles the cylindrical indentation and protrusion, a bonding agent that is positioned between the pair of main body sections, and a connector having a proximal end that is secured between the pair of main body sections and a distal end that is positioned away from the pair of main body sections.
