I was out poking around next to a creek in the area of Kentucky where the beautiful Ky agate is sometimes found. I think it's pretty rare any more but still couldn't help but hope I might find something pretty while we were there for a picnic and hike. This was really the only thing I found that was very interesting (from a lapidary standpoint anyway! ) and was hoping someone could tell me what it is. I've only got a workforce saw so was only able to get a small piece off - and only that with the use of a hammer and screwdriver to finish as the piece is just too bulky. Anyway - here are some of the pics - I was hoping to find a piece of Ky agate and got excited when I saw this but knew the chances were pretty slim. Now I'm just curious as to what it really is. Outside of rock - another view - Inside - and the piece that I got off - closer view (and better representation of the colors) - Any ideas? Thanks for looking!

Looks like some kind of agate pseudomorph maybe after coral or an aragonite formation....Mel

Could it be petrified wood?

I've not quite mastered the Moh's scale yet - but when I take a nail to it, in some parts it seems to remove material (the greenish splotch) in others (the pinkish area) it leaves a silver streak. So some spots are harder than others. I was thinking something along the lines of what Mel suggested - if I understand what he's suggesting anyway... There are lots of fossils to be found in that area and though I'm not real familiar with fossilized coral, for some reason that's what came to mind when I started looking at this rock. I was hoping when I cut into it, it would become a little more obvious that it was a fossil - but wasn't really sure what I was expecting to see - maybe more of a pattern or distinctness to it. I don't really see that but it did seem to be agate-y, which I was happy enough to see! I'll have to see if I can get a bigger slice off of it somehow. My little WF saw had about all it could handle with this little slice - and I practically had to stand on my head at that! Thanks for the thoughts on this - it's been bugging me to not know what it is!

It looks like Unakite to me. Here are some pics of ones I picked up this morning in Alice Springs, Australia. Hope this helps. Marg
