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.

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.

A ring system having a first ring and a second ring, each ring having an inner circumferential surface, an outer circumferential surface, a first surface and an opposing second surface. The first ring and the second ring each have a fastener on the respective first surfaces and the first ring and the second ring each releasably fasten to each other causing the first surfaces of the rings to abut. Each outer circumferential surface has an outer diameter, the outer diameter being the largest diameter of the outer circumferential surface. The first ring and the second ring each have an edge where the first surface and the outer circumferential surface intersect. The diameter of the edge of the first ring is equal to the outer diameter of the first ring and the diameter of the edge of the second ring is equal to the outer diameter of the second ring.

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.

Disclosed is a jewellery article including at least one first part having a first cylindrical inner face in which there is provided at least one groove, at least one second part having a second cylindrical inner face provided, in the extension of same, with at least one rim, the at least one rim being arranged facing the at least one groove, and at least one attachment member mechanically secured to the at least one rim of the at least one second part and extending into the at least one groove of the at least one first part; the at least one groove, the at least one rim and the at least one attachment member being configured to allow the at least one first part and the at least one second part to rotate freely with respect to each other.

Systems and devices for a ring wearable cover with non-deformable circumference are described. The removable cover for a wearable ring device may include a ring-shaped surface configured to extend around a full circumference of the wearable ring device when the removable cover is in a mounted state on the wearable ring device and one or more mounting features that are disposed on the ring-shaped surface. The one or more mounting features may be configured to interact with a surface of the wearable ring device to lock the removable cover onto the wearable ring device when the removable cover is in the mounted state on the wearable ring device. In some cases, a diameter of the removable cover is unchanged while the removable cover transitions from the mounted state on the wearable ring device to an unmounted state off of the wearable ring device.

Methods, systems, and devices for a functional cover are described. A removable cover (e.g., a functional cover) for a wearable ring device (e.g., a ring wearable) may include one or more electrical components positioned at least partially within the removable cover. The removable cover may further include a first electrical component exposed to an external surface of the removable cover, the first electrical component configured to contact (e.g., physical and electrically contact) a second electrical component of the wearable ring device, such as when the removable cover is in a mounted state on the wearable ring device. The first electrical component may be further configured to transfer electrical current, data, or both, between the one or more electrical components of the removable cover and one or more additional electrical components of the wearable ring device.

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.
