These stones have become harder to get as access to this remote area has become limited.
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.
These are not grounding stones metaphysically as one may initially think. They are very high Vibration, 3rd eye, useful in meditation & astral / Visionary Work.
