The mineral aggregate '''[[bloodstone]]''' is a cryptocrystalline mixture of quartz that occurs mostly as [[jasper]] (opaque) or sometimes as chalcedony (translucent). The "classic" bloodstone is opaque green jasper with red inclusions of hematite. The red inclusions may resemble spots of blood, hence its name. The name heliotrope derives from various ancient notions about the manner in which the mineral reflects light. Such notions are described, for example, by Pliny the Elder.
A significant development in '''[[clairvoyance]]''' research came in the 1930s, when J. B. Rhine, a parapsychologist at Duke University, introduced a standard methodology, with a standard statistical approach to analyzing data, as part of his research into extrasensory perception. A number of psychological departments attempted to repeat Rhine's experiments, with failure. W. S. Cox from Princeton University with 132 subjects produced 25,064 trials in a playing card ESP experiment. Cox concluded, "There is no evidence of extrasensory perception either in the 'average man' or of the group investigated or in any particular individual of that group. The discrepancy between these results and those obtained by Rhine is due either to uncontrollable factors in experimental procedure or to the difference in the subjects."


Bloodstone was called "stone of Babylon" by Albertus Magnus and he referred to several magical properties, which were attributed to it from Late Antiquity. Pliny the Elder (1st century) mentioned first that the [[magician]]s used it as a stone of invisibility. Damigeron (4th century) wrote about its ability to make rain, solar eclipse and its special virtue in [[divination]] and preserving health and youth.

A significant development in clairvoyance research came in the 1930s, when J. B. Rhine, a parapsychologist at Duke University, introduced a standard methodology, with a standard statistical approach to analyzing data, as part of his research into extrasensory perception. A number of psychological departments attempted to repeat Rhine's experiments, with failure. W. S. Cox from Princeton University with 132 subjects produced 25,064 trials in a playing card ESP experiment. Cox concluded, "There is no evidence of extrasensory perception either in the 'average man' or of the group investigated or in any particular individual of that group. The discrepancy between these results and those obtained by Rhine is due either to uncontrollable factors in experimental procedure or to the difference in the subjects."
