Transcript
Sapphires and rubies are among Earth’s most valuable gems. They’re both varieties of the same mineral, corundum, which is made from aluminum and oxygen. After diamonds, corundum is the hardest mineral.
During the global flood, continental plates rapidly crashed into one another. The intense pressure and heat transformed flood deposits into super-hard rocks with gems. Magma, rising from the mantle, picked up these gems, bringing them to the surface. Others were brought up by crashing plates.
We only have sapphires and rubies because of the processes of the flood of Noah’s day.
