A ring and method of manufacturing a ring which may include: an outer ring, in which a second carbide composed of a combination of tungsten carbide, iron group carbide or carbonitride is mixed with a metal binder phase at a predetermined ratio, in which the outer ring is divided into a first outer ring and a second outer ring formed in a shape corresponding to each other; an inner ring separately and/or independently assembled between the first and second outer rings, in which the inner ring includes an outside inner ring that forms an outer circumferential surface of the ring and an inside inner ring that forms an inner circumferential surface of the ring; ring fitting parts formed on the first and second outer rings, respectively, such that both sides of the outer and inside inner rings are press-fit; and assembling protrusions formed on the first and second outer rings, respectively, to be inserted into the outer circumferential surface of the inside inner ring to maintain a firm assembly between the outer ring and the inner ring for a long period of time.

A ring type wearable terminal includes: a first ring that has a recessed portion formed on a side surface thereof; a second ring that is bonded to the first ring and that covers the recessed portion; and a communication unit that is housed in the recessed portion. The recessed portion is filled with an adhesive agent. The adhesive agent filling the recessed portion bonds the first ring and the second ring and also fixes the communication unit to the recessed portion so as to protect the communication unit. This allows the strength of the ring type wearable terminal to be improved.

A stackable jewelry system including first and second bands which can be stackable to form a stacked configuration in which (i) the first and second bands dispose in coaxial relation, and (ii) a second protrusion of the second band can be capable of radial alignment with a first opening of the first band.

This disclosure includes jewelry that has an arcuate first body with opposite first and second ends, each end defining an opening. An arcuate second body has an end with a hinge element in the opening of the first end of the first body to provide pivot capability between the first and second bodies. An arcuate third body has an end with a hinge element in the opening of the second end of the first body to provide pivot capability between the first and third bodies.

A method for assembling at least a first element and a second element to form, once assembled, an external component for a portable device, including the steps of: a) making the first element; b) making the second element; c) arranging at least a first groove in the first element and at least a second groove in the second element; d) placing and holding the first and second element end-to-end with at least a third connecting element which is inserted and locked in the first and second grooves.

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.
