I forgot to mention that I don't see any translucency in the rock - it's real black. It looked real dark green when dry, but now that I'm polishing it, it looks black, especially wet.

My geologist friend will slice off a piece and we'll see how thin I'd have to be before it is translucent.

He's got a saw at work that will slice a U.S. Dime (10 cent piece) in half - long way! The kerf is measured in micronsor something crucial like that.
