Crystal is a high quality form of glass which creates light reflection. All pieces are delicate and need to be cleaned with care.When moving objects, always carry one object or one part of an object at a time. It is best to place your hands around the body of the object rather than using an existing handle, rim, or  spout for support. In general, it is not a good idea to routinely wash the pieces. Each time a piece is handled for cleaning there is a greater risk of breakage through accidents and mishandling. It is better to protect pieces from soiling and dust in the first place, rather than washing them too often.
