It is pretty famous, and holds a special place in my heart, for it is on the cover of the first "mysteries" book I ever read, when I was a teenager.
The "evidence" revolves around whether or not ancients had the tools to make it or not. Anyone who believes that "advanced civilizations" existed long ago will ignore this news.
I, however, believe it is a fake...
Whatever legends are attached to the crystal skull of the British Museum in London, there is one indisputable fact. No other single object in the museum's extensive collection has acquired such a cult following from New Age devotees.
Now, however, science can finally set the record straight and in doing so shatter one of the most enduring myths of an object steeped in historical fantasy. The crystal skull is a fake.
A detailed analysis of the crystal skull's surface has revealed that it was cut and polished with the sort of rotating wheel common in the jewellery houses of 19th Century Europe but absent in pre-Columbian America.
Historians and scientists believe that the crystal skull was cut from a piece of Brazilian rock crystal by a lapidary in Europe, possibly Germany, and then sold to collectors as a genuine relic from the ancient Aztec civilisation of Mexico.
... The scientists took impressions of the skull with the same flexible resin used by dentists to take precise impressions of teeth. This revealed the minute rotary scratch marks around the eye sockets, teeth and cranium and was clear evidence that the sculpture had been cut and polished with a wheeled instrument - and the Aztecs did not have the wheel.
