This product is called the Dancing Pearl. It is very exciting. It uses the inside curved surface of a relative standard sea shell to act as a reflector of a pearl that is suspended at its focal point. The result is a magnification of the pearl in the reflector. As you walk across the room, your pendant moves causing movement of the pearl and it’s magnified image. It sure to get you noticed and is a great conversation piece. Go ahead have some fun with it.
