In an under component having a proximal end and a distal end, the under component comprising a cylindrical portion extending from the proximal end to the distal end; wherein the proximal end includes a rim that extends laterally from the cylindrical portion and that is flush with the proximal end; the rim extending from the cylindrical portion, wherein the rim includes a proximal edge and a distal edge. An over component having a proximal end and a distal end and a rim having a proximal edge and a distal edge, wherein the distal end of the under component extending to a position flush with a proximal edge of the rim of the over component, wherein the distal end of the over component extending to a position flush with a distal edge of the rim of the under component. A central component, wherein the central component is coupled to the over component, and the over component is coupled to the under component

A jewelry ring sizing system is disclosed that has an outer jewelry ring, an endless elastomeric ring, and an inner endless ring press-fit within the outer jewelry ring in a concentric orientation relative thereto with the endless elastomeric ring encapsulated between the outer jewelry ring and the inner endless ring.

This is a particular style of decoder ring. It is based on a spinner ring that is worn on the finger. It has a band that spins, and a small window cut out of that band. The window allows characters on the surface below to be read one at a time as the window passes over them.

A ring-type wearable device is disclosed. The disclosed ring-type wearable device comprises: an outer ring member; an inner ring member separably inserted into the outer ring member; a sensor unit disposed in the outer ring member; and a control unit disposed in the outer ring member so as to be electrically connected to the sensor unit, wherein the sensor unit can maintain constant sensitivity in correspondence to the thickness of the inner ring member.

In accordance with an embodiment, a jewelry arrangement system having interchangeable components includes: a plurality of jewelry pieces, each jewelry piece having at least one through hole formed in a portion thereof, and each jewelry piece is adapted to be arranged in a particular orientation relative to the other jewelry pieces within the plurality of jewelry pieces; and an alignment tool adapted to align different combinations of the at least one through holes formed in the plurality of jewelry pieces, to create a plurality of jewelry arrangements, including at least a first jewelry arrangement and one or more additional jewelry arrangements, using the plurality of jewelry pieces.

A ring-type wearable device is disclosed. The disclosed ring-type wearable device comprises: an outer ring member; an inner ring member separably inserted into the outer ring member; a sensor unit disposed in the outer ring member; and a control unit disposed in the outer ring member so as to be electrically connected to the sensor unit, wherein the sensor unit can maintain constant sensitivity in correspondence to the thickness of the inner ring member.

An article of jewelry is provided that includes a base with one or more channels in an outward facing surface portion of the base. One or more inlays can be placed in the one or more channels. The inlays can be formed of an elastomeric material that elastically holds the inlays intension within the channel and allows repeated removal and addition to the channel without fracturing.

The present invention refers to the field of precious objects, and in particular to the field of goldsmithing, jewelery, with particular reference to rings. It should be noted that the present invention can also refer to the field of bijoux or the like. Particularly interesting for the present invention are the rings and the problem of their measures.

A ring system having a first ring and a second ring, each ring having an inner circumferential surface, an outer circumferential surface, a first surface and an opposing second surface. The first ring and the second ring each have a fastener on the respective first surfaces and the first ring and the second ring each releasably fasten to each other causing the first surfaces of the rings to abut. Each outer circumferential surface has an outer diameter, the outer diameter being the largest diameter of the outer circumferential surface. The first ring and the second ring each have an edge where the first surface and the outer circumferential surface intersect. The diameter of the edge of the first ring is equal to the outer diameter of the first ring and the diameter of the edge of the second ring is equal to the outer diameter of the second ring.
