An interchangeable jewelry device includes a locket including a body and a cover. The body defines a cavity, and the cover attaches to the body by a hinge. A case includes a socket sized to receive the body of the locket. A first magnet is positioned on an exterior surface of the body of the locket. A second magnet is positioned on an interior surface of the socket of the case that mates with the first magnet of the body of the locket when the locket is positioned in the socket of the case.

This invention is a jewelry locket having an NFC chip which is capable of transmitting digital content to a smart phone by retrieving information from the NFC chip with the NFC chip housed within a metal jewelry structure having an internal compartment fixedly holding the NFC chip sufficiently away from the walls to permit wireless transmission between the chip and a smart phone.

A piece of toy jewelry made from novelty jewelry elements that either interconnect or are joined by a jewelry mount. Each novelty jewelry element has a central spindle. A roll of material is wound on each central spindle. The roll of material is selectively dispensed from the piece of toy jewelry. The central spindle in each novelty jewelry element has a first end and an opposite second end. The ends of the spindle can interconnect either directly or through the use of a mount. The roll of material on the spindles present the appearance of elongated beads when formed into toy jewelry.

A construct having an aesthetic form is adapted to please a wearer and to be worn by the wearer. The construct provides a structure having a wearer connection element such as a ring, a chain, a wristband, a pin, a clasp, a clip, and a body piercing element. The functional elements including a fluid reservoir in which at least two fluids are disposed, and a motion generation system are integrated on the structure, The motion generation system is functionally affixed to the structure so as to agitate the at least two fluids, causing a visual animation effect. The construct, in particular jewelry, may have incorporated therein one or more channels and/or reservoirs containing one or more fluids wherein the fluids as well as the forms and surface treatments of channels/reservoirs are selected possess physical properties so as to promote a defined interaction with the one or more fluids. The interaction influences the visual appearance of the device, such device optionally being made at least in part of precious metals, natural components such as pearls, and/or precious stones.
