Abstract: A jewelry display stand including a vertical post assembly mounted on a base. A plurality of arms, serving as hanger elements for jewelry or other merchandise, radiate from the post. The arms co-operate with anti-removal elements on the post that prevent merchandise from being removed from the spokes. In one embodiment a ring engaging the tips of the arms provides the anti-removal elements. In another embodiment the anti-removal elements are a set of spokes above the arms. Either the arms or the spokes are movable up and down and are spring-biased upwards, to a position in which the arms are separated from the anti-removal elements and merchandise can be removed from or placed on the arms. A cap on the post engages the movable elements, holding them down, and keeping the arms engaged with the ring or spokes. A slot in the cap allows one arm or spoke to rise to the non-engaging position, and the cap is rotatable about a vertical axis so that the slot can be aligned with any selected arm or spoke. Thus, merchandise can be removed from only the selected arm, reducing the risk of pilferage.
