Opaque Selenite TV Rock, sold singly, average size - 3cm x 3cm x 2cm
Natural Selenite in this formation, is fibrous. Many columns of optically clear fiber like crystals grow together to form a larger mass. Each Individual fiber allows light to pass through in one direction only, whilst in other directions light simply reflects off. In addition the value of the light that passes through can also be slightly magnified.
Picture 2, shows TV rock over some text print, so you can see effect it has. Its great formation of the natural rock, that many find very interesting, especially children.
Note- there is another crystal which has very similar optical properties - Ulexite.
