Tiger iron is not a single mineral but a mixture with varying proportions of reddish-brown jasper, shiny metallic magnetite layers and shiny golden tiger's eye.
The individual layers are partially curved due to pressure deformation and the glowing tiger's eye in particular then looks even more interesting.
This piece has been cut and polished to a first-class finish - the raw material comes from the areas where it was found in North Australia.
