Another thing to note: I have a card that was included with my "T.V. Rock". It states the crystallography as: "NaBaB5O9 - 8H20". Yours says "Ca" instead of "Ba".
I hate to say it, but your sample looks more like gypsum than ulexite. Satin spar gypsum is transparent with fractures while ulexite is more opaque with discolored freckles and usually without fractures. At 2:14, ulexite would display text clearly on the surface, even from a side angle in the near dark, and your piece looks blurry unless viewed from directly above. It looks like you got gypped! (haha gypsum, gypped, the similarity makes sense don't you think?)
@kiwiqueen sorry but that ulexite. gypsum doesnt do this, and it has a 'bladed' crystal structure, and can be scratched with the fingernail. all of these things ulexite doesnt have.
I am just back from a field trip to Dingle,Co Kerry 3days ago and my note book still has not dried out.The area we went to was a semi arid desert -type area about 300my...........be nice if we drifted south again :-)
Iceland spar is calcite which doubly refracts light. Which means you see double vision. Ulexite is a true fiber optic, it transmits light from the base of the stone to the surface. Both are cool effects though.
l live in japan.
this movie is nice.

@stevenscottoddballz It is supposed to be Ca, not Ba. Ulexite is hydrated sodium calcium borate hydroxide.

Thank you VERY much. I'll make the correction on my card.

No it is definately Ulexite. The video doesn't do it justice, and it is obviously not gypsum when studied up close. But thanks for the comments.

Wow! That's nice... do you have another sample? How much it's cost if you want to sell it?

what so special about this stone? only transparent?
nahrafqifahs 3 years ago
No not just transparent but it transmits the image to the surface of the stone so it looks like the words are being shown on a screen.

It's hard to capture the coolness of Ulexite with a camera. Cool vid!
