What is Prophecy Stone?
The prophecy Stone is a trading name for an unusual material that's a limonite (originally stated to be hematite) pseudomorph after marcasite or pyrite. In this case, the mineral itself has been replaced by limonite, but the limonite pseudomorphs still preserve the original shape of the marcasite or pyrite crystals.
