Ulexite is a natural fiber-optic stone called the TV stone. When placed on writing, the image will appear to be reflected within the stone. This sedimentary crystal is usually found in borax evaporite deposits in dry lakes or arid regions. Main deposits are located in California, Nevada, & Chile.
Honestly, ulexite is probably one of the coolest stones that has ever come into existance! It literally looks like a television screen when you hold it over an image or writing & I absolutely love it.
Metaphysically, ulexite is known to be used in telepathy as well as channeling emotions & energies.
