Prophecy Stone is an unusual gemstone that is a pseudomorph of Limonite, Hematite after Marcasite or Pyrite, meaning that it originally formed as a solid crystal nodule of marcasite, but was altered into a limonite material.
 This rare mineral is from Egypt's Libyan Desert and is found in the same area as Libyan Desert Glass! . 
Prophecy Stones resonate strongly with the Third Eye Chakra and are a very high vibration srone.
They are excellent at helping one also receive guidance about mundane, boring matters and practical choices that must be made.
These are approx 2-3cm in size
