A light-emitting jewelry piece includes a gemstone, a head, and a mounting. The head is configured to interconnect the gemstone to the mounting. The mounting is arranged to secure the light-emitting jewelry piece to a person or a personal adornment.

This disclosure generally relates to light-emitting jewelry systems with light emission controlled by a Bluetooth unit. The light-emission may be provided by LED electronics. The jewelry may be women's\men's earrings. The illumination of the jewelry may be of low, medium, or high intensity. In a preferred embodiment, the illumination may be of low intensity. The light-emitting jewelry system may further include a battery unit.

A compact precision illumination source mounts on a finger of a user for providing localized illumination for precision tasks such as surgical procedures and other tasks performed in dark or confined spaces. A frame having a circular or arcuate shape engages the finger, and secures an enclosure having a small but powerful bright, light focused on a predetermined region defined by the end of the digit that is likely the activity region for an instrument grasped by the digit.

Luminaires, rechargeable illuminating personal ornaments and charging bases are disclosed. An example luminaire comprises a charging base and a rechargeable illuminating personal ornament. The charging base comprises a power cable connectable to an external power source and a power connector. The rechargeable illuminating personal ornament is connected to the charging base and has a shell, a light source attached to the shell, a rechargeable power source, located in the shell and connected to the light source, a corresponding power connector, defining an opening in the shell and coupled to the rechargeable power source. The power connector of the charging base is coupled to the corresponding power connector of the rechargeable illuminating personal ornament.

A medical alert necklace is formed with a container loop wearable around a neck of a user and contains a medical dose as an ingestible for the user. The medical alert necklace includes a personalized pendant that uniquely identifies the user as having a medical condition, and includes a quick response (QR) code accessible to identify an emergency contact person for the user and/or medical information about the user. The medical alert necklace can also include an alert system that receives an alert activation from a smartphone and activates to warn of a hypoglycemic condition of the user. The medical alert necklace has a fastening system to secure the container loop around the user, such as a magnetic clasp. The fastening system includes a plunger press-fit into the container loop. The ingestible is distributable for user consumption through the plunger, and the container loop is refillable through the plunger.

The invention relates to a piece of ear jewelry having at least one ear part to be worn on each ear of a user, wherein each ear part has a jewelry body, to be worn in a predetermined wearing position on an outside of the ear, and a retaining device for retaining the jewelry body in the wearing position on the ear, wherein the auditory canal of the ear remains free. The piece of ear jewelry incorporates all of the following electrical components completely and so as to be invisible from the outside: a microphone device, a loudspeaker device and a communication unit for providing a bidirectional, wireless communication link to a portable terminal of the user, in order to use the communication link to transmit a microphone signal from the microphone device to the terminal and to receive a loudspeaker signal for the loudspeaker device from the terminal.

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.

A method of forming a diamond bulk object includes heating a crystalline material on a support disposed in a volume defined by a chamber, introducing into the volume a reactant gas including a hydrogen-containing component and a carbon-containing component, depositing a plurality of layers of diamond by chemical vapor deposition (CVD) to form at least a portion of the diamond bulk object on the support, and forming a predetermined color gradient in the plurality of layers of diamond.

A personal jewelry article includes a light source coupled to a power source and located within a compartment interior of a shank of the personal jewelry article. A stone is connected to the shank above the compartment. The light source emits light through the stone and the stone alters the light emitted by the light source.
