Tiger Iron is composed of 2 billion year old sedimentary deposits of three different stones: Tiger's Eye, Jasper and Hematite. Tiger Eye and Jasper are members of the quartz family, and hematite is, of course, an iron oxide.
Metaphysically, Tiger Iron is about passion and creativity.
It has a hardness of 7 on the Mohs scale.
This Tiger Iron comes from South Africa.
