Slab of Tiger Iron

Tiger Iron, a combination of Golden Brown Tiger Eye, Hematite, and Red Jasper, exhibits the metaphysical properties of its components as well as its own. It is part of the Banded Iron Formation, a sedimentary sequence laid down some 2.5 billion years ago. The black parts of this polished slab are thin layers of hematite, and the red layers are jasper. The bright golden areas are part of the same layers, made of tiger-eye quartz. It forms when iron-bearing quartz replaces the fibrous mineral crocidolite.
