Moldavite
Moldavite is nicknamed “The Stone of Transformation” and is thought to have been created from a meteorite that crash-landed 15 million years ago. It is believed to have crashed in the present-day Czech Republic, more specifically, the Bohemian Plateau. As you can imagine, pieces are scattered throughout the area and are found almost at random. The impact itself was estimated at six trillion megatons and is believed to have passed completely through the Earth's crust into the planet's core.
"Moldavite is a powerful aid for meditation and dream-work, as well as increasing one’s sensitivity to guidance, intuition and telepathy, and the ability to understand messages sent from higher realms."
