Prophecy Stones are a very unique stone. They are a pseudomorph, Limonite / Hematite After Marcasite / Pyrite. The original Crystal Structure remains from the Marcasite / Pyrite but has morphed / changed completely into something else. These are from a remote area of the White Desert in Egypt and are not seen very often. For the past 3 years I have purchased the entire inventory from the source in Tucson. These are not grounding stones metaphysically as one may initially think. They are very high Vibration, 3rd eye, useful in meditation & astral / Visionary Work.
