A smart ring includes an antenna chip and a metal ring used as an antenna, and the antenna chip is electrically connected to the metal ring to form an antenna circuit. The metal body of the smart ring is designed as a composition structure of the antenna circuit, that is. the antenna is integrated into the metal ring, the space for accommodating the antennas and the cost for additional physical antennas are saved, and the design flexibility and the competitiveness of the product are improved. Nickel-zinc ferrite is unnecessary, which can reduce the cost. The ring can keep the radiation characteristic of the circular antenna that is not susceptible to the interference from human body. The metal body of the ring is a metal structure, which can fulfill both of strength requirement and texture requirement of the structure, and at the same time has good antenna characteristics.

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 comprised of two individual bands, an inner band 101 and an outer band 102, that through a methodical materialization process and design of the inner band 101 and outer band 102 are interlinked, but not fused together, to allow the outer band 102 to revolve around the inner band 101.

The embodiments set forth a jewelry accessory setting for an array of stones, such as gemstones including for instance diamonds, where said stones are arranged in accordance to a gradient of known quality, such as cut, clarity, carat or color. The jewelry accessory may include bars between each stone to prevent color contamination. The jewelry accessory alternatively sets forth natural stones together with treated or synthetics stones. The jewelry accessory is useful when utilized in a method of valuing stones of unknown quality, such as by a purchaser assessing the value of a piece of jewelry with stones of unknown quality by comparing such potential purchase to the jewelry accessory set forth herein.

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 flexible wearable ring assembly wherein a circular band portion is designed to encircle a human finger and a top portion is designed to hold a removable portion displaying a logo or other symbol. The flexible wearable ring assembly is made from a silicone-based compound or other flexible material. The flexible wearable ring assembly may include a radio-frequency identification tag containing data that may include blockchain data. The flexible wearable ring assembly may include other text, symbols, patterns, or color codes for either or both presenting information and accessing other data or systems.

A wearable article over skin includes opposite circular edges. The wearable article further includes an inner surface and outer surface defined between the opposite circular edges. The inner surface includes a curved profile adapted to be extended across the opposite edges and a plurality of aeration vent grooved over the inner surface of the wearable article. Furthermore, the curved profile extending up to the opposite edges and the plurality of aeration vent on the inner surface creates an aeration path between the skin and the wearable articles. The aeration path facilitates fluids to flow between the skin and the wearable article.

A wearable electronic simulated smoking device is provided for delivery of a desired active ingredient responsive to a user's inhalation through the device. The device includes an elongated tubular member having at least one fixedly arcuate shaped portion to at least partially encompass a portion of a user's body and is releasably retainable thereat. The device includes a vaporization chamber supplied with a vaporizable smoking composition and enabled by a controller to generate vapor from the vaporizable smoking composition and add the vapor to air drawn through the device.

A personal ornament that includes: a base portion that includes a pair of right-and-left base-side engaging ring portions, and fixes and holds a gemstone; and a frame portion that includes a pair of right-and-left frame-side engaging ring portions to be coupled to the base-side engaging ring portions, and that supports the base portion, the base portion and the gemstone being supported to be swingable with respect to the frame portion. The personal ornament also includes a protective member that protects, from an outside, at least the frame-side engaging ring portions, and coupling parts of the base-side engaging ring portions with respect to the frame-side engaging ring portions.

An article of jewelry comprising; a frame; and a decorative element secured within the frame, wherein two-dimensional array of optical phase shifting structures is embedded in the decorative element; wherein the two-dimensional array of optical phase shifting structures project an image when illuminated with a light source.
