In 1990, Italian geologist Angelo Pitoni purchased strange blue stones from a Fula Chief in Sierra Leone🇸🇱 in West Africa. The people claimed the rocks were brought by visitors from the sky.
Pitoni returned home to Europe and brought the mysterious rocks to a university for testing.
The results showed the stones didn’t match any known mineral. The researchers couldn’t explain why the rocks retained a blue color. When a small piece was pulverized and viewed under a microscope, there was no blue color visible. Heating the stone to high temperatures would not alter the mineral. Acids would not break it down.
Further analysis showed that 77.17% of the stone was Oxygen. The remaining composition was Carbon, Calcium, and an unknown organic compound. The age of the Sky Stones may be as much as 55,000 years old.
