Prophecy Stones are unusual stones found in the Sahara Desert. Their name comes from the man that discovered them after he had a "prophetic vision" while meditating with one. Prophecy Stones are a Pseudomorph of limonite, hematite after marcasite or pyrite. The crystals morphed or changed into another mineral over time leaving the original crystal's shape. They are found in the same area as Libyan Desert Glass Tektites. We gift wrap every order and offer free shipping in the US.
