A method for rendering a gemstone traceable, includes the steps: providing an invisible marker, wherein the marker is unambiguously identifiable, fastening the marker in a placement location of the gemstone, and acquiring marking information that includes that this unambiguously identifiable marker is fastened to this gemstone. The marker can be transported to the placement location in a manner in which it is suspended in a carrier fluid. An additive, for example a primer or a starting material for a surface coating of at least a part surface of the placement location, can be added to the carrier fluid.

An item with engraving associable with a web content includes an item body, made of metal or metal alloy, and at least one engraving made on the body of the item, or on an element embedded or mounted in the item body. The at least one engraving represents at least one respective code which is associated with the item and is also associated with a web connection able to show a web content, related to the item. The item includes a ring and/or a piece of jewelry and/or a jewel and/or a watch and/or a medal and/or an item made of a precious metal. The at least one engraved code includes a QR-code and/or an alphanumerical code and/or a bar code.

A wearable article over skin includes opposite circular edges. The wearable article further includes an inner surface and outer surface defined between the opposite circular edges. The inner surface includes a curved profile adapted to be extended across the opposite edges and a plurality of aeration vent grooved over the inner surface of the wearable article. Furthermore, the curved profile extending up to the opposite edges and the plurality of aeration vent on the inner surface creates an aeration path between the skin and the wearable articles. The aeration path facilitates fluids to flow between the skin and the wearable article.

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 item of jewelry includes a first and second glass component. The first component includes a base layer with cremains deposited on a front surface. The second component is the same size and shape as the first component so that its outer edges align with those of the first component. The second component includes an image of a print placed on a substrate. The first component is placed on, and annealed to, the second component such that the cremains are sandwiched between the base layer and the substrate to form a durable image of the print on glass.

An identification locket having a novel construction and tracks extending the entire periphery of the exterior housing and being entirely embedded therein. The tracks form c-shaped channels in the side walls and being adapted to house at one guide ball and the guide being further characterized by a guide rope and bail being placed thereon. The guide ball is freely rotatable and is configured to rotate within the tracks. The side walls and the tracks have at least on mating projecting edge. The guide ball is configured to rotate within the track with backward or forward movements and the track is configured to rotate a plurality of the guide balls relative to each and wherein the guide rope freely rotates on the outside of the tracks.

Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including one or more colorants, a first surface, a second surface, and a recess in the first surface not reaching the second surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes one or more colorants. The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.

Embodiments for a removable zipper charm with marketing receptacle are provided. The attachment includes a medallion, a connector ring, a connecting mechanism, and marketing material. Generally speaking, these components are structured such that the connector ring is attached to the medallion at the edge of the medallion, the marketing material is engraved or attached to the medallion, and the connecting mechanism is fastened to the connector ring and thereby the medallion. The connecting mechanism can also be simultaneously fastened to a zipper slide or a zipper pull tab, and this architecture allows a user to use the attachment as a zipper tab replacement or extension while promoting marketing material as desired.

External part for a timepiece or piece of jewellery, this external part being produced by means of a polymer matrix in which piezochromic molecules are dispersed that change from a first stable state to a second stable state while changing colour under the effect of applied pressure.
