Vivianite "Corpse Crystal" Curio Vial

Ever hear of a crystal that forms on bodies? Meet Vivianite — the spooky, little-known mineral known as the "Necro-Crystal."  Don't worry, it's not haunting—just science. As a body starts to rot, phosphorus trapped in bones and teeth gets released. If there's iron and water present? Kaboom. Vivianite begins to crystallize—directly on the remains.  This foreboding blue-green crystal has been found on fossilized ancient bone, on mammoth tusks, and even on freshly dead human bodies. Yes, yes indeed.  Centuries buried. or a few years—Vivianite does not judge. Death is its playground.  It's beautiful. It's bizarre. And it grows on the dead.
