The sub-assembly includes a bayonet fit between two edges and two wings of skirts of the first component and the second component. The first component and the second component are able to occupy an assembled and indexed position. The first component or the second component including for this purpose, in part in the thickness of the first skirt or second skirt, an elastically deformable zone including a lug for angular indexation between the first component and second component, cooperating with an indexation limit stop of the other component.

A method for creating a jewelry ring made of multiple stacked rings that are counter-rotatable with respect to each other. Using precise CNC machining, two ring blanks are formed to have complimentary shaped bearing ends that interlock with each other to prevent axial dislocation, but also provide complimentary bearings so that the rings are counter-rotatable to each other. These ring blanks are sized relative to each other so that after being formed, they can be aligned at their complimentary ends and the smaller ring enlarged to snap into the larger ring. The method also requires precise interior diameter smoothing and post-processing, so that the slight separation between the two stacked ring blanks cannot be felt by the wearer. A two-ring and a three-ring version are fully disclosed, but by logical extension this method can be used to make any number of stacked rings.

The disclosure refers to jewelry or rings worn on fingers with embedded decorative jewels. The technical problem to be solved is to increase the reliability of fixing the decorative jewel by eliminating its mobility and expanding the jewelry's artistic and aesthetic significance. The piece of jewelry contains a decorative Jewel located in a setting and an annular jewelry part with a boss. On the surface of the boss, there is at least one longitudinal groove and an annular part that intersect with each other. The setting is made hollow with a cylindrical inner surface and may be installed to the boss along the inner surface. On the inner surface there is at least one protrusion that may be engaged in the groove of the jewelry part.

An annular piece of jewelry includes a plurality of coaxial ring elements connected to each other and moveable in relation to each other, where the ring elements include an inner ring element and two outer ring elements wherein the inner ring element and the outer ring elements can be moved in relation to each other into various positions. The outer ring elements cover different outer circumference surface regions of the inner ring element. The inner ring element is arranged in an axial direction between the two outer ring elements or between parts of the outer ring elements. The two outer ring elements and the inner ring element are coupled to each other in such a manner that the inner ring element can be moved in axial direction by rotating one of the two outer ring elements in relation to the other one of the two outer ring elements.

An interchangeable jewelry setting system that allows for the insertion, removal and replacement of ornamental elements onto a jewelry piece is provided. The jewelry piece may comprise any type of or piece of jewelry onto which an ornamental setting may be fitted such as, for example, a ring, necklace, earring, bracelet, broach, pin, etc. Likewise, any ornamental element may be disposed on the interchangeable setting of the invention, such as, for example, a metallic engraving, ornamental design element, etc.

A near field communication ring configured to be worn by a user is provided. The NFC ring may include at least one metal ring having a gap, a chip, and an antenna, wherein the chip and the antenna may be fixed to the at least one metal ring having a gap, and wherein the chip, using the antenna, is configured to provide a near field communication with an external device.
