Abstract

A piece of jewelry for indicating mood and usable as a pendant or the like in the form of a miniature traffic light having three apertures of substantially the same size spaced in vertical alignment with one another and having a cylindrical inner surface. A carrier having a mating cylindrical surface is fitted inside of the housing. The carrier includes three vertically stacked sections colored red, amber and green which are relatively movable with respect to the housing and indexably arranged for selective individual viewing through the respective top, middle and bottom apertures. For moving the carrier it has an operator which extends through the housing for convenient fingertip manipulation to a color condition which depends upon the mood of the wearer. In the preferred embodiment of the invention the selected color is brought into register with the corresponding aperture by peripheral shifting, whereas in an alternate embodiment the desired color is brought into a condition of register by axial shifting. The alternate embodiment moreover has provision for simultaneous display of the same color on at least three sides of the device. Another embodiment may use transparent colored sections with a source of electric light, a battery and a switch.
