11. Skystone Is An Artifical Rock

“Skystone” or “Stone of Heaven” is an odd type of blue stone and was discovered during archeological excavations in Sierra Leone, West Africa. Angelo Pitoni, the archeologist who found the stone, was puzzled by its appearance, so he sent it to be investigated by laboratories of the University of Geneva, the University of Tokyo etc. The results were the same. The stone did not exist in nature and was not even similar to any type of rock. It is composed of 77% oxygen, along with traces of silicon, sodium, calcium and carbon. Also, its blue color indicates it was artificially colored. Another mystery related to the Skystone is that the stone was found in soil layers dating to at least 12000 BC.
