Specimen of TV Selenite from Morocco

It is called TV Selenite because, if you place it over an image, the image appears to be at the top of the rock, as on a TV screen. The fibres of the selenite act as optical fibres, transmitting light along their lengths by internal reflection. Lots of detailed information can be found on the web.
