Interesting points about the Crystal Skulls:
Crystal skulls are not uncommon or terribly mysterious.
The crystal skulls are human skull hardstone carvings made of clear or milky white quartz, known in art history as “rock crystal”, claimed to be pre-Columbian Mesoamerican artifacts by their alleged finders; however, none of the specimens made available for scientific study have been authenticated as pre-Columbian in origin.
Thousands are produced every year in Brazil, China, and Germany. But there are a handful of these rather macabre objects that have fueled intense interest and controversy among archaeologists, scientists, spiritualists, and museum officials for more than a century.
There are perhaps a dozen of these rare crystal skulls in private and public collections. Some are crystal clear, others of smoky or colored quartz.
Some are actual human size and of very fine detail, while others are smaller and less refined.
Many believe these skulls were carved thousands or even tens of thousands of years ago.
Although nearly all of the crystal skulls have at times been identified as Aztec, Toltec, Mixtec, or occasionally Maya, they do not reflect the artistic or stylistic characteristics of any of these cultures.
The Mixtec occasionally fabricated skulls in gold, but these representations are more precisely described as skull-like faces with intact eyes, noses, and ears.
The Maya also carved skulls, but in relief on limestone. Often these skulls, depicted in profile, represent days of their calendars.
