I work at a tile store and spend all day looking at really nice marbles and travertine, which brings me to my question. Has there been use of, marble, or some sort of stone in a guitar application? I'm referring more specifically to inlays and maybe binding than anything. The only concern would be that natural stone is porous, so it needs to be sealed, and the polish would eventually wear, which would be fine after a wet sand. Anyone ever hear of anything?
There's a lot more marbles than the white/black veined ones you commonly see, so keep an open mind!
I haven't heard of any, but this idea kicks ass.
