Ulexite. Ulexite (hydrated sodium calcium borate hydroxide, also known as TV Rock or TV Stone), is a mineral that has a structure of closely-packed parallel crystal fibres. The fibres transmit light along their lengths by internal reflection. Ulexite is an example of fibre optic properties occurring in nature. Shown here is a ulexite specimen placed over 'ULEXITE' written on a white paper. | |
