15 Fun Facts About Pyrite

Pyrite is named after the Greek word for fire. The name "pyrite" is derived from the Greek word "pyr," which means fire. This is due to the fact that pyrite can create sparks when struck against metal or flint. The sparks are a result of the sulfur content in pyrite reacting with air.
