Crystal gazing or crystallomancy is a method for seeing visions achieved through trance induction by means of gazing at a crystal. Traditionally, it has been seen as a form of divination or scrying, with visions of the future, something divine etc., though research into the content of crystal-visions suggest the visions are related to the expectations and thoughts of the seer.

Fortune telling is the unproven spiritual practice of predicting information about a person's life. The scope of fortune telling is in principle identical with the practice of divination. The difference is that divination is the term used for predictions considered part of a religious ritual, invoking deities or spirits, while the term fortune telling implies a less serious or formal setting, even one of popular culture, where belief in occult workings behind the prediction is less prominent than the concept of suggestion, spiritual or practical advisory or affirmation.
