Ulexite, often referred to as “TV rock” or “television stone,” is a borate mineral composed of hydrated sodium calcium borate. Its chemical formula is NaCaB₅O₆(OH)₆·5H₂O. Ulexite is notable for its unusual optical properties, specifically its natural fiber optic ability to transmit light along its fibers, which gives it the appearance of projecting images or text from its surface when placed on top of them.
