Abstract: Jewelry/personal articles in the form of sets of items which may be sold in pairs or groups, each article of the group being provided with the RFID circuitry unique to that pair or group and an electrical display which will illuminate when two or more of the items of the group are in proximity to each other, but not requiring one to be in physical contact with another. In one embodiment the personal article comprises a heart necklace and a circular pendant, each provided with an electrical display such as a lamp and a normally open battery powered electrical circuit interconnected with the electrical display and uniquely coded RFID containing a tag and reader. Operation of the electrical display is initiated by bringing the two articles within proximity of each other and the uniquely coded RFID circuitry of the one item recognizes the matched uniquely coded RFID circuitry of another item of the same pair or group.
