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.

Disclosed is a ring shield. The ring shield enables a user to wrap around the ring shield on a body part of the user, such as user's finger to protect a ring comprising a ring stone worn upon the finger of the user. The ring shield comprises a ring shield body adapted to be wrap around the ring shield on the user's finger to protect the ring comprising the ring stone worn upon the finger of the user; at least one anchor hole adapted for putting the ring stone through it; and at least one fitting slot adapted for completing a circle by putting the ring stone through in the selected at least one fitting slot.

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. In some cases, the functional cover may wireless connect with the ring wearable. The removable cover may further include a first inductive component within the removable cover, where the first inductive component is configured to wirelessly communicate with a second inductive component of the wearable ring device when the removable cover is in a mounted state on the wearable ring device. The first inductive component of the removable cover may be 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.

Adjustable ring protectors to be worn on a digit of a user that include a first ring shape, an interior comprising at least one interior material, an exterior comprising at least one exterior material encasing the at least one interior material, and the exterior comprising an exterior surface including a texture. The first ring shape includes a first end, a second end, and a first open space between the first end and the second end. The least one exterior material includes a soft material. The at least one interior material includes a deformable material. The at least one interior material and the at least one exterior material are configured to minimally deform producing a second ring shape configured to securely fit the adjustable ring protector on the digit of the user. The second ring shape includes the first end, the second end, and a second open space. In some examples, the adjustable ring protector includes a first end cap coupled to the first end and a second end cap coupled to the second end. In some further examples, the exterior of the adjustable ring protector includes an inner surface comprising a inner surface texture and an outer surface comprising an outer surface texture, wherein the inner surface texture is different from the outer surface texture.

Ring protector made of non-elastic or elastic materials produced by common manufacturing techniques including, but not limited to, 3D printing or by skilled hands, to snuggly fit around a ring and completely surround the outside of a ring and any incorporated designs, stones or settings. The ring protector may contain padding or cushion material within any design recess to further protect the ring and any incorporated designs, stones or settings. Ring protectors made according to principles of this invention protect rings from damage while the ring both on and off the ring-wearer's hand.

A protective cover for a smart ring comprising an annular member formed from flexible material adapted to stretch over a ring and wherein in use and when fitted to a ring it covers the exterior surfaces of the ring and also being configured such that it does not affect the contact between internal sensors of the smart ring and the skin of the ring wearer's finger.

Presented is a ring protector or a ring guard for protecting a ring worn on a finger. The ring protector includes a pair of annular members, and a base interconnecting the annular members. The base extends partially along the circumference of the annular members leaving an open slot at the opposing side of the base for insertion of the ring to be protected.
