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 stones 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. https://www.ancient-...ed-west-africa/
