A Calcium-sodium hydrated borate mineral, which exhibits a unique fibre optic property. 

When placed over a newspaper or picture, the image is carried through capillary fibres in the rock to make it visible through the rock at the top. When viewed from the side, the fibres are distinctly visible.. 

 Ulexite is nature’s example of the fibre optic light tubes that now carry millions of telephone calls, data and T.V. pictures around the world.

First mined in Death Valley USA, Ulexite is sought after for its industrial, agricultural  and pharmaceutical uses.  Today it is mined at U.S. Borax’s large open pit in Boron, CA.
