Product Overview
Magnetite forms as an accessory mineral from an igneous melt. As it cools, the iron in its atomic structure becomes magnetized. Magnetite's attraction to magnets and distinctive black streak make it an excellent tool for identification exercises.
While each specimen will vary slightly in shape, size and color, it will measure approximately 1" in length. Pack of 12. Each set is individually packaged, labeled & barcoded for easy identification and storage.
