Shattuckite tumbled stone

"Shattuckite is a highly spiritual stone that heightens vibration. It brings clear psychic vision and also aids in understanding and communicating what is seen. This crystal is particularly useful in cases where past life experiences have closed down one's metaphysical abilities. Shattuckite is helpful during channeling, as it is strongly protective. It reaches a high vibration, ensuring that the purest source is contacted. Shattuckite can be used to develop psychic abilities such as automatic writing and telepathy." - from The Crystal Bible
