A ring assembly including a shank having a band defining a head mounting area with a through hole defined through the band in the head mounting area. The through hole defines internal threads; and a head including a mount with a post extending therethrough, the post including an area of external threads configured to engage the internal threads to releasably secure the head to the shank. Methods for forming and demonstrating ring assemblies are also disclosed.

A vented or decorative finger ring and its method of manufacture that employs a co-injection mold casting of the vented or decorative finger ring that is formed with joined outer and inner rings where the inner ring includes a plurality of interconnected lateral and longitudinal slots or grooves, where the lateral slots or grooves are space apart and extend from the inner ring edges that each connect to a series of linked longitudinal slots or grooves formed around the inner ring that extend to the inner surface of the outer ring, forming air flow paths across the inner ring, between the inner ring edges.

A vented finger ring and its method of manufacture are provided. The vented ring includes an outer ring portion, an inner ring portion, and an anti-stretch element positioned between the outer ring portion and the inner ring portion. The inner ring portion includes lateral grooves connected to inner grooves, the connected lateral grooves and inner grooves forming at least one fluid conduit from a first side of the vented ring to a second side of the vented ring. The method includes injecting a first material into a first mold to form an outer ring portion, injecting a second material into a second mold to form an inner ring portion, and positioning an anti-stretch element between the outer ring portion and the inner ring portion. The second mold includes at least one feature on a surface thereof, the at least one feature corresponding to connected lateral grooves and inner grooves on an inner surface of the inner ring portion.

A wearable electronic apparatus includes an inner ring that is configured to be in direct contact with a user and the inner ring is split to define a first inner ring end and a second ring end. A link element is configured to connect the first inner ring end and the second inner ring end. An outer ring is arranged around and in contact with the inner ring, where the outer ring is adjustable in diameter between a plurality of size settings. A housing structure for housing electronic components, where the housing structure is arranged to at least partially surround the inner ring and the outer ring.

A vented or decorative finger ring and its method of manufacture that employs a co-injection mold casting of the vented or decorative finger ring that is formed with joined outer and inner rings where the inner ring includes a plurality of interconnected lateral and longitudinal slots or grooves, where the lateral slots or grooves are space apart and extend from the inner ring edges that each connect to a series of linked longitudinal slots or grooves formed around the inner ring that extend to the inner surface of the outer ring, forming air flow paths across the inner ring, between the inner ring edges.

A ring for wearing by a user includes a rigid outer annular body and a flexible inner annular body. In one embodiment, the outer annular body is a rigid material formed from a process other than injection molding, and the inner annular body is flexible and formed from an injection molded process. The outer annular body is attached to the inner annular body. The inner annular body may be machined to curve from longitudinal ends of the inner annular body to an inner surface of the inner annular body after the inner annular body is joined to the outer annular body in order to provide a comfort fit. Alternatively, the inner annular body may be molded with the comfort fit curvature. In one embodiment, the outer annular body has at least one strain relief recess in an inner surface thereof, and the inner annular body fills said strain relief recess.

Articles of jewelry comprising an ornamental support structure (100), a first aperture (108), a second aperture (110), a first annular element (104) received by the ornamental support structure (100) through the first aperture (108), and a second annular element (106) received by the ornamental support structure (100) through the second aperture (110). The first aperture (108) and the second aperture (110) may be shaped to limit lateral movement of the respective received annular elements (104, 106) while allowing the annular elements (104, 106) to rotate relative to the ornamental support structure. The first annular element (104) may be entwined with the second annular element (106).

A ring for wearing by a user may include a rigid outer annular body and a flexible inner annular body. The outer annular body may be a rigid material, and the inner annular body may be flexible and formed from an injection molded process. The outer annular body may be attached to the inner annular body. The inner annular body may be machined to curve from longitudinal ends of the inner annular body to an inner surface after the inner annular body is joined to the outer annular body in order to provide a comfort fit. The inner annular body may be molded with the comfort fit curvature. The outer annular body may have at least one strain relief recess in an inner surface thereof, and the inner annular body may fill the at least one strain relief recess.

A jewelry item includes an inner ring base, an inner ring arranged on the inner ring base, and a decorative body. A slot is provided on an outer surface of the inner ring base. The inner ring defines a through hole at a position corresponding to the slot. The decorative body includes a mounting column. The mounting column passes through the through hole and is limited in the slot. The decorative body is limited to the inner ring base by a triple limit locking structure, which completely prevents the decorative body and inner ring base from detaching. The limit locking structure is very simple and ingenious. The jewelry item is able to be assembled and disassembled by hands without using tools. Compared with the prior art, the jewelry item is more convenient for a user to assemble, which improves assembly time and efficiency.
