Anyone have any idea what this is? It has some agate in the top center of it but the rest is a mystery to me. From the matrix, I thought it was mushroom jasper/rhyolite, but the insides doesn't appear to be. Any ideas?

I believe that is Cold Mountain t-egg out of Mexico. It looks a lot like Butterfly jasper (another t-egg) but tends to have yellow ares with red line (like this one) and often agate in the center with some drusy vug.

Daniel, The picture you have below is very much like what I have although mine has much less agate. However, the little I know about t-eggs is that they are mostly round. Correct? This one had a couple good sized nodules attached which I cut off (not shown) but otherwise was pretty much shaped like any other(non-round) piece of rough. The rough was about eight or nine lbs.

Nope - too pink to be Cold Mountain and the pattern is wrong. I don't think I've ever seen opalite water lines in a Cold Mountain, either. I'm pretty sure it's a slice of Butterfly Jasper from Mexico. Hard stuff and polishes great and often has water line agate/opalite. I think some folks call it "Mariposa Jasper". (Not to be confused with "Mariposite", which is green and white.) I'm guessing that maybe the two jasper nodule types may be from locations very close to each other. C-ya, Rick

maybe butterfly. both are from near each other in Mexico. if it is older material, then definitely butterfly t-eggs especially when double or multiple are not round in cross section. Here is one I own: I do have slices of cold mountain that is tan/flesh, not pink, but I was not sure if the color in you photo was exact. I was attending to the yellow/red in the top left. both materials similar.
