This specimen of Tiger Iron out of the banded iron formation (BIF) has been collected, cut and tumble polished by us as seen in this video: https://youtu.be/yJVM0ldAdxw?si=f-lib76umnLi_TTU

Banded iron formations are 1.5 to 3.8 billion years old which makes them the earliest known rocks.

In some parts of the world Tiger Iron is also called Mugglestone.
