Man-made? Is this the same as Rainbow Calsite? From a mine in Mexico that I have seen a picture of a guy standing next to a seam in a rock wall as tall as he was?

Please post the photo or a link to the photo.

Like I said, picture that I saw in a cab class I was in two years ago. That's why I was curious if we were talking the same thing since I thought it was a completely natural material from a single mine in Mexico. My instructor even went so far as to explain how they managed to stabilize it there which was one of the reasons it was so expensive.

Here's a couple of links that might interest you:

I guess I'm a natural-born skeptic and the fact that Colbaugh's investigator wasn't allowed access to the mine itself tells me everything I need to know.

Yeah, it's pretty much settled that this is man made, possibly from industrial run off as opposed to deliberately made, at least originally, but nonetheless, not natural.
