Colour:orange, brown, red-brown
Name:Named after pilgrims traveling to Santiago de Compostela, who carried it from other parts of Spain and used it as a kind of talisman, although the mineral does NOT occur in Santiago de Compostela itself.

A variety of Eisenkiesel

In Spanish mineralogical literature, the name is traditionally used exclusively for the red-brown (hematite-included) variety of authigenic quartzes from continental gypsum-bearing marls of the Triassic Keuper formation. (They may also be found occasionally in younger Tertiary or Quaternary sediments, but in these cases the crystals were eroded out of the Keuper F.)

Two types are common: 1. Isolated biterminated crystals, 2. hedgehog-like spheroidal aggregates. Both characteristically occur as "floaters".
