The term crystal gazing denotes several different forms of a variety of objects, and there are several schools of thought as to the sources of the visions seen in the crystal gazing trance. Crystal gazing may be used by practitioners&mdash;sometimes called "readers" or "seers"&mdash;for a variety of purposes, including to predict distant or future events, to give character analyses, to [[fortune telling|tell fortunes]], or to help a client make choices about current situations and problems.

With respect to the tool or object used to induce the crystal-gazer's trance, this can be achieved with any shiny object, including a [[crystalline]] [[gemstone]] or a convex [[mirror]]&mdash;but in common practice, a [[crystal ball]] is most often used. The size of ball preferred varies greatly among those who practice crystallomancy. Some gazers use a "palm ball" of a few inches in diameter that is held in the hand; others prefer a larger ball mounted on a stand. The stereotypical image of a [[Romani people|Romani]] woman wearing a headscarf and telling fortunes for her clients by means of a very large crystal ball is widely depicted in the [[Mass media|media]] and can be found in hundreds of popular books, advertising pages, and films of the 19th, 20th and 21st centuries. The pervasiveness of this image may have led to the increased use of fairly large crystal balls by those who can afford them.

Books of instruction in the art of crystal gazing often suggest that the ball used should be perfectly spherical (that is, without a flat bottom) and should be supported in a wooden or metal stand. If made of glass (e.g. [[lead crystal]]), it should be free from air bubbles but may be colored. If carved from natural crystalline stone (such as [[quartz]], [[beryl]], [[calcite]], [[obsidian]], or [[amethyst]]), it may display the natural coloring and structure of the mineral from which it was fashioned. Some authors advise students to place a [[seal (emblem)|sigil]], seal, or [[talisman]]ic emblem beneath a clear sphere, but most do not. Most authors suggest that the work of crystal gazing should be undertaken in a dimly-lit and quiet room, so as to foster visions and more easily allow the onset of a trance state.{{Citation needed|date=March 2009}}<!--which books tell this?-->

Some practitioners claim that crystal gazing engenders [[visionary]] experiences and [[preternatural]] and/or [[supernatural]] [[insight]], while other practitioners and researchers assert that the visions arise from the [[subconscious]] mind of the crystal gazer. Some authors note that the two positions are not mutually incompatible, and that the possibility of showing the gazer's subconscious mind does not preclude the possibility of seeing the future or other supernatural insight.<ref>{{cite web|url=http://backpackerverse.com/crystal-gazing/|title=Crystal Gazing|date=7 January 2016|website=Backpackerverse|last1=Vazquez|first1=Sol|access-date=18 May 2016}}</ref>
