So I had this piece for awhile, I posted in a fossil forum about it being burnt petrified or fo fossilized wood. I started to look at it again and began to notice that it had some translucency. I then wet it and began to take more pics.

The smooth side of this piece has a crazy green opal like sheen that I never noticed. Thought it was neat, so I'm sharing it.

Wood can be fossilized—petrification, agatized or even opalized… It depends on conditions and minerals available. I can say that the color green, when it comes to petrified wood, is one of the more rare colors that exists and tends to command more value. I’m sure pictures don’t do that justice, so it’s hard to say exactly what is going on there… Either way, any petrified/fossilized wood Is pretty cool stuff and I enjoy it all… Couple different examples I have… The piece marked rare petrified wood is actually from a really old collection that was in an auction box I purchased for $3, probably 25 years ago and it had a bunch of cool slabs from various trees, including different palm trees that were in there…all great stuff!

You're totally right, i had posted pics of this piece awhile ago. It wasn't until just the other day I happened to wet it and looked at it under light. It doesn't show that green unless it's wet and under light at the right angle. It appears transparent/glass like, obsidian type properties where it's been seemingly chipped it's shiny.

Only showing green when wet, held at certain angle and under light.

Do you have any pictures in natural light. It appears their are bubbles in your material but the pics are out of focus so it could just be artifacts.

From the pictures in this thread it appears you have industrial slag. Probably a flux scraping from the top of an iron smelt.
