TigerEye has long been considered a quartz replacement of asbestos, otherwise known as a pseudomorph. The asbestos is gone, so it's harmless to cut. However, new research into the origins of tiger eye shows tiger eye is actually not a pseudomorph. The fibrous structure of tiger eye creates chatoyance and also gives it a definite grain structure.

Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral.
