So, I've been reading a lot lately about Escher stones, but a search of the forum doesn't show up very much information - my assumptions are that they are a natura finishing stone (like a yellow Coticule) and that there are regular Eschers and the more desirable yellow-green Eschers. Thats pretty much all that I've been able to pick up.

A Google search of Escher only bombarded me with a bunch of pictures from some cross-eyed architect with a serous case of astigmatism (no wonder engineers think architects are a bunch of flakes!)

Here, build this one!

Up the Down Staircase

This is just creepy!

This one's OK

...anyhoo...what's the appeal of Escher hones? Where do they come from? And why are they (evidently) so high priced?

-whatever
