The Seba library treats Crystal Ball in 7 passages, across 3 authors (including Greer, Mary K., Pollack, Rachel, Mathieu, Ingrid).
Crystal balls are among the most outstanding examples, including Dr. John Dee's crystal ball of smoky quartz with which he made prophecies for Elizabeth I.
Greer grounds the crystal ball in a documented historical lineage of sacred and prophetic use, from Mayan quartz skulls to Elizabethan court divination, establishing its legitimacy as an occult instrument with deep cultural precedent.

I have found crystals to be a good tool to use in conjunction with Tarot readings and meditations, especially for harmonizing and balancing the atmosphere, and for helping me focus my attention and clarify my intentions.

Next to each of the four outer candles, place a crystal pointing in toward the center. Under each crystal, place the Ace from the suit that corresponds with that direction.
Greer embeds the crystal within a ritual circle-casting structure coordinated with elemental Tarot correspondences, treating the crystal as a directional energy conductor within sacred space.

Any device which produces a 'random' pattern will serve this function... Dice and mixed cards and spinning wheels all cut through the conscious mind's control of the outcome.
Pollack provides the theoretical substrate for all divinatory instruments including crystal gazing, arguing that randomizing or attention-focusing devices produce synchronicity by bypassing conscious control.

Magical thinking centers on one's belief system rather than on the facts... Magical thinking as spiritual bypass occurs when someone uses his beliefs about a rit
Mathieu implicitly contextualizes scrying objects like crystal balls within the problematic of magical thinking and spiritual bypass, where belief in ritual efficacy may substitute for genuine psychological work.
