A personalized holographic jewelry item which has the appearance, in non-coherent light, of a precious stone (which can have the exceptional quality, clarity and size). The item preferably also includes a second hologram layer, which through use of coherent-optical processing, produces an additional positive effect. By using the principle of waveband separation, the invention enables reconstruction of personalized/security data to identify and secure said jewelry item. In other applications, the second hologram enables the item to be used as an identification device for general application, while at the same time displaying holograms of precious stones. The jewelry item might additionally include a ruby, serving, besides a display effect, the purposes both of accumulating and discharging one or more pulses of coherent radiation and at the same time being made secure by means of above mentioned security data with secure user's access. In another aspect, the invention enables the user to create/synthesize unique display holograms on biological carriers, such as nails or hair, by very simple and relatively inexpensive techniques.
