Tiger Iron Crystals - Western Australia
Highly polished tiger iron tumbled stones in a slightly larger size.
Some varieties of tiger iron can resemble the mineral tigers eye, but it's not the same stone.
Tiger iron, correctly known as a banded iron formation (BIF), occurs in rocks that date back 1.8 to 2.5 billion years. It's composed of layers of minerals rich in iron.
Widely used for decorative purposes, tiger iron consists mostly of hematite or magnetite, red jasper and tigers eye.
Banded iron formations are believed to have formed before oxygen was present in Earth's atmosphere.
Oxygen, which was being given off as a waste product by microscopic aquatic organisms, reacted with dissolved iron in the seawater, which led to the development of iron oxides on the seafloor. Over time, these gradually became banded formations rich in iron and silica.
Tiger iron crystals are also known as Mugglestone.
Tiger iron comes from the Pilbara region of Western Australia.
