Tiger Eye Sphere. Tiger Iron is a magnetic mineral that formed between 543 and 2.5 billion years ago. Tiger iron consists of part Jaspar, hematite and Tiger eye. It was formed over thousands of years by mats of microbes living on the seafloor. As these slimy mats of Cyanobacteria died thin layers of minerals built up as new layers of living microbes replaced the old colony. These fossils of colonies of Cyanobacteria are know as stromatolites and are the very first large detectible evidence of life on our planet. This large 3.45 inch diameter magnetic sphere weighs 2.7 pounds and has been polished revealing bands of red and burnt orange Jasper, dark brown hematite and beautiful iridescent yellow Tiger's eye. Tiger's eye is a chatoyant silicon dioxide mineral that gets its color from iron oxide. This gem quality Tiger's eye comes from the Pilbara region of Western Australia. This beautiful sphere comes with a plastic stand for display.
