The Seba library treats Quartz in 8 passages, across 4 authors (including von Franz, Marie-Louise, Eliade, Mircea, Greer, Mary K.).
the crystal of quartz is a hexagonal prism. The statement is quite true in so far as an ideal crystal is envisaged. But in nature one finds no two crystals exactly alike, although all are unmistakably hexagonal.
Von Franz uses the quartz crystal as a paradigmatic case to argue that natural, individual actuality exceeds the ideal type, thereby grounding the Chinese and Jungian preference for concrete, synchronistic reality over abstract causal law.
, Psyche and Matter, 2014thesis
The rock crystals that play an important part in the initiation of the Australian medicine man are of celestial origin... Baiame sits on a throne of transparent crystal... The crystals detached from his throne are 'solidified light.'
Eliade establishes that quartz crystals in Australian shamanic initiation carry a cosmological pedigree as fragments of the sky-god's throne, identifying them with celestial luminosity and the power of ascent.
, Shamanism: Archaic Techniques of Ecstasy, 1951thesis
the hala, the Semang medicine man, cures with the help of quartz crystals, which may be obtained directly from the Cenoi (Chenoi, Chinoi, Cinoi). The Cenoi are celestial spirits. Sometimes they also live in the crystals.
Eliade documents the Semang hala's use of quartz as a diagnostic and curative instrument inhabited by celestial spirits, reinforcing the pattern of quartz as a condensed point of contact between the shaman and transpersonal, sky-derived power.
, Shamanism: Archaic Techniques of Ecstasy, 1951thesis
Using a quartz crystal as the weighted end of a pendulum makes it into an extremely sensitive psychic current detector and amplifies your intention in using it.
Greer articulates a practical-esoteric theory in which quartz amplifies psychic intention when used as a pendulum, positioning the mineral as a material extension of the unconscious will.

Dr. John Dee's crystal ball of smoky quartz with which he made prophecies for Elizabeth I... the famed Mitchell-Hedges skull... was carved from one piece of extremely clear quartz crystal.
Greer situates quartz within a historical lineage of sacred and oracular objects, framing clarity of the mineral as a prerequisite for prophetic and divinatory use.

Crystals held in your hand act to magnify both the healing intention and the energy flow through your hands.
Greer describes quartz as a material amplifier of healing intentionality, integrating the mineral into a therapeutic model that combines visualization, chakra energy, and archetypal Tarot imagery.

In a way similar to the visualization process above, enter your crystal, find your dreaming room, make your dream intention clear, and fall asleep inside your crystal.
Greer prescribes quartz as a ritual container for dream incubation, treating the crystal's interior as an imaginal space capable of structuring and preserving the dreaming psyche's intentions.
