I picked Iowaite[Mg4Fe(OH)8Clx2-4(H2O)] because it has the name of a state in it and I think thats pretty cool. It’s found mostly in Sioux county, Iowa and has perfect cleavage(thatswatshesaid). It is bluish green, greenish white, or honey yellow. Its platy and forms in sheets. It is relatively soft, with a hardness of 1.5. It leaves a white streak and has a greasy luster. It is also transparent and is not radioactive.
