    Abstract: A jewelry display for rings which enables prospective customers to try on the rings and which prevents ring theft. The device includes a frame having a member in turn having a front display face through which a plurality of slots are provided so as to receive the shank portions of the finger rings while the ornamental portion thereof is outwardly displayed from the front surface. A reel having a spring retractable line attached thereto is disposed behind each of the slots. The line is connected to the ring so that it may be drawn away from the display surface as when a prospective customer is trying on a ring for size or style and so as to require return of the ring to its respective slot when released.
