crystal skull

Crystal skulls are human skull hardstone carvings made of clear, milky white or other types of quartz (also called "rock crystal"), claimed to be pre-Columbian Mesoamerican artifacts by their alleged finders; however, these claims have been refuted for all of the specimens made available for scientific studies.

Crystal skull refers to a number of human-like skull carvings made of quartz crystal and their associated myth and research.
