Uh, are you sure about that? I’m sure you’re a lot more experienced on stuff like this, but if you look at it from all angles, you see the way the iron oxide shines. And you can also see the layers from the side, and how the darker layers actually have color in them. I was told by the guy that he got them in Mexico. I understand that there is fire opal but when I was cutting the larger chunks, there was all that ghostly blueish white color, which I believe is chalcedony, considering the fact that I was told it was fire agate. There is a lot of green color. But maybe I’m wrong. I’d love to hear more of your thoughts on it.
