Derivation:From G L Ulex, a 19C chemist who discovered the mineral
Formula: NaCaB5O9.8H2O

The crystals of Ulexite transmite light rather like fibre optics. So if you look at something through Ulexite, it appears on the top rather than through it, which looks rather strange. It is sometimes called TV rock.

Ulexite refracts an image so it appears on top of the stone rather than through it. The first photograph, taken from the side, shows the 'ul' of the word 'ulexite' appearing above the rest of the word. The second photograph was taken from the top.
