This reddish brown tiger iron does have some nicks and imperfections. Here's what Judy Hall author of the Crystal Bible says about crystals with imperfections.
Tiger iron is made up of layers of tigers eye, hematite and red jasper. Correctly known as a banded iron formation (BIF), only stone from the Pilbara region of Western Australia is known as tiger iron. Banded iron formations are found in many countries around the world.
When used for its metaphysical properties tiger iron is a stone of power. It combines the energies of three minerals into one stone. Hematite works with the brain to help improve memory, red jasper increases strength and endurance and tigers eye is for protection.
