A system for reversibly mounting an object, the system comprising a base having a first region and a second region in rotatable communication with the first region such that in a first configuration, the regions are not coplanar and in a second configuration they are. Also provided is a system for removably mounting objects, the system comprising a base having a first end defining a first cross section; and a lever having a second end defining a second cross section, the lever in rotatable communication with the base such that in a first configuration, the ends are not aligned, and in a second configuration the lever is nested within the base such that the ends are aligned to form a continuous geometric shape defining an aperture adapted to receive a carrier.

A jewelry article for a garment of clothing includes a backing layer having a first side and a second side, a jewelry layer coupled to the first side of the backing layer, a first fastening member, and a second fastening member. The first fastening member is coupled to at least one of the jewelry layer or the backing layer and extends along the backing layer. The first fastening member is configured to detachably couple the backing layer to a corresponding fastener coupled to a garment of clothing. The second fastening member is coupled to at least one of the backing layer or the jewelry layer and is configured to detachably couple opposing portions of the backing layer.

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.

A modular finger ring assembly is provided. The ring assembly includes a circular band portion adapted to encircle a human finger. The band portion includes a notched portion located at its top. The ring assembly includes a metallic component configured to removably engage to the notched portion of the band portion. The metallic component includes a top wall, a pair of side walls, and a pair of horizontally extending flaps extending inward from the bottom of the side walls, forming a retaining space for receiving the notched portion. The metallic component further includes prongs extending upward from the top wall and configured for retaining one or multiple precious stones placed on top of the top wall.

In an aspect, there is provided an elastic ring-based ornament making device for constructing an elastic ring-based ornament that includes at least one elastic ring and a plurality of ornamental members positioned thereon. The elastic ring-based ornament making device includes an elastic ring support including a plurality of extension arms which are movable between retracted and extended positions. When the arms are retracted, the elastic ring support supports the at least one elastic ring in a first state. When the arms are extended, the elastic ring support supports the at least one elastic ring in a second state. The at least one elastic ring is stretched more in the second state than in the first state. The arms when extended are spaced from one another sufficiently to permit mounting of the ornamental members on the at least one elastic ring between the arms.

An item of jewelry having a plurality of interchangeable decorative elements, the jewelry comprising an elastically deformable holding element and the decorative elements comprises a retaining bolt that is protruding from a core of the decorative element and which comprises a head at its end and comprises a constriction between the core and the head, wherein sections of the holding element project into the constrictions.

A modular finger ring assembly is provided. The ring assembly includes a circular band portion adapted to encircle a human finger. The band portion includes a notched portion located at its top. The ring assembly includes a metallic component configured to removably engage to the notched portion of the band portion. The metallic component includes a top wall, a pair of side walls, and a pair of horizontally extending flaps extending inward from the bottom of the side walls, forming a retaining space for receiving the notched portion. The metallic component further includes prongs extending upward from the top wall and configured for retaining one or multiple precious stones placed on top of the top wall.

A setting (1), including, aligned along an axis for driving into a bed (8) of a piece of jewellery or timepiece (9), an upper body (15) including a first surface (2) to receive a component to be set (10), a setting element (4) to hold the component (10), and a lower body (16) including a second front surface (6), between which bodies (15; 16) a deformable area (7) is plastically deformable under the action of an axial driving force greater than a predetermined driving force, to bring the setting (1) into a stressed state wherein the deformable area (7) is irreversibly deformed and/or fractured, in the form of a clot radially pushing back a peripheral surface (3) of the setting (1) towards a lateral wall of the bed (8), or/and in the form of a fault radially pushing back the upper body (15) towards this lateral wall.

A system for reversibly mounting an object, the system comprising a base having a first region and a second region in rotatable communication with the first region such that in a first configuration, the regions are not coplanar and in a second configuration they are. Also provided is a system for removably mounting objects, the system comprising a base having a first end defining a first cross section; and a lever having a second end defining a second cross section, the lever in rotatable communication with the base such that in a first configuration, the ends are not aligned, and in a second configuration the lever is nested within the base such that the ends are aligned to form a continuous geometric shape defining an aperture adapted to receive a carrier.
