It's not very big specimen but its pretty cool, I found it out at my fire agate spot, actually just a hill over where there's purple and blue Chalcedony, I'm guessing those Schiller effects are caused by iron oxide layers, anyone ever seen something like it?
Thanks, I've never seen these Schiller effects before, I found these between where I dig up fire agates and collect purple and blue Chalcedony, it's like a mixture of the two with pinkish maroon Schiller effects. I think it's a new find, at least it is for me.
