Glimmer Rock ( Wood Stone )

That's a lovely piece of rock  Does it feel like rock or petrified wood?


I would have thought the orange streaks would have 'bled' if they were an iron contaminant after being left outdoors.
Try leaving it in a bucket of water for a few days and see what happens. If it doesn't develop rusty streaks, it should be OK.



Iron sulphide is pyrite or fool's gold. I have a sample sitting on the cupboard in the lounge (I collect minerals in the shape of eggs) and it is definitely pale gold rather than orange.

Iron oxide is orange - commonly called rust. I would have expected the rock to look rusty if there was iron in it.
