An apparatus and a method are provided for a breakaway silicone ring configured to reduce finger and hand injuries. The breakaway silicone ring includes a rigid core coupled with a molded silicone portion and an optional NFC chip. The rigid core comprises a series of curved segments arranged in a loop configuration. A union between each pair of adjacent segments is configured to maintain the loop configuration while allowing for separation upon application of an external force. The unions may be comprised of magnetic ends of the segments, or sockets at one end of the segments that receive protrusions at the other end of the segments. The silicone molded portion is exterior surface layer disposed around the core. The silicone molded portion may include openings that allow direct observation of portions of the core. The portions of the core can include any of smooth surfaces, molded designs, and printed logos.

Exemplary embodiments of a ring and ring assembly are provided. In one embodiment, a ring assembly is provided having an inner ring, an outer ring having a groove within an inner portion of the outer ring that fits the inner ring, and a mechanism provided on the outer ring allowing the outer ring to be opened to place the inner ring within the outer ring. The outer ring can have an opening through which a jewel on the inner ring can project when the outer ring is closed. The outer ring can have a design that surrounds the jewel on the inner ring.

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.

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.

A halo effect ring has an inner halo fixedly connected to an inner ring, and an outer halo fixedly connected to an outer ring. Both rings can have gems in settings and other ornamentation, and when combined, the halos are in concentric circles, when viewed from above, with at least part of the inner ring or it's setting or other attached parts rising through the outer halo. Another outer ring is hingedly connected to the first outer ring, and removably connected to the outer halo such that the halo can sit flush with a top side of the outer rings.

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

Exterior sub-assembly for a timepiece or watch or piece of jewelry, comprising a first component and a second component, arranged for a bayonet fitting between two rims and two wings comprised in the first component and the second component, and able to occupy an assembled and indexed position of the first and second components, this sub-assembly including a third component in the form of a ring, inserted between the first and second components and comprising a ring-like element housed inside a groove of the first or second component, this third component including a rotational stop with respect to the first or second component, and a resilient area with radial relief, cooperating in an angular indexing arrangement with a lug of the first or second component which is free to rotate with respect to the third component.

A ring assembly, including: a circumferential component including a protruding member; and a decorative component, having decorative indicia disposed on an upper surface, and a socket opening disposed in a lower surface having dimensions corresponding to the protruding member, the ring assembly being movable from an initially disassembled state to a fully assembled state in which the protruding member is inserted in the socket opening, and engages the decorative component.
