“Mineral of Death”

This blue mineral - Vivianite - grows on dead bodies and turns them blue.

“If you were to get up close and personal with Ötzi the Iceman – the 5,000-year-old mummy of a tattooed, deep-voiced man who died and was frozen in the Alps – you’d notice that his skin is flecked with tiny bits of blue. At first, it would appear that these oddly bluish crystal formations embedded in his skin are from freezing to death or some other sort of trauma, but it’s actually a mineral called vivianite (or blue ironstone) and it happens to form quite often on corpses left in iron-rich environments.”
