Dazzling Reminders of Biblical Truth

This is Ken Ham, often a radio and TV program guest on the Bible’s reliability.


Sapphires and rubies are some of the most valuable gems found on earth. They’re both varieties of the same mineral, corundum. It’s made from aluminum and oxygen. After diamonds, corundum is the hardest mineral.

During the Flood, continental plates rapidly crashed into one another. The intense pressure and heat transformed the deposits of the Flood into super-hard rocks—with gems. Magma, rising from the mantle, then picked up these gems and brought them to the surface. Others were brought to where we can find them near crashing plates.

We only have sapphires and rubies because of the Flood. They remind us of the Bible’s true history.
