Patrick, my husband, went to a new customers house a couple of weeks ago to do windows, roof and gutters. The lady that bought the house said that the previous owner was a rock collector. The entire landscape was made from his collection. The new owner doesn't know anything about rocks and didn't seem too interested in learning. Patrick asked if he could buy the collection but she turned him down saying that the pretty rock landscape was one of the selling points that made her choose to buy this particular house. She did give him a couple of rocks though to bring home and asked if he could bring a polished piece back to her the next time he comes out ;D I knew what the other couple of rocks were but this one has me stumped. It appears to be river tumbled. Fortification agate lines run across the outside of the rock which I rarely see: We cut it in half and the fortification lines run all the way through... Any ideas on the name or locality of this stone? The purchased home it came from is in Western Washington but I don't know anything about the previous owner or where he collected from. Thanks in advance for anyone that might possibly be able to help me!!!

Krystee, the agate looks like it is in a jasper type material. Doesn't look like a mud from the cut pic. Very cool lookin piece. Have you got the idea for the cab layout yet? Then again, that could be a shelf piece depending on the ID. I'll be following this one

I'd say its a septarian nodule where the filling between shattered sedimentary rock is chalcedony rather than the more commonly seen calcite. Utah has quite a few varieties of both sorts...Mel

I didn't know there was septarian with agate, but that sounds right. the one Helen linked is the typical non-agate type so that only helps to show the crus/fracture pattern in septarian, the obvious feature here is the fortification, as you already spotted.
the key is whether the surround is jasper, or softer (like septarian)
do you think the veins with banding would compose nice cabs?

Reminds me of a septarian nodule. Don't really know. Very attractive!

(Edit 9/9)
It feels like jasper however I didn't do any tests on it. Clean solid cut and a nail marks it nicely on the agate and the surrounding stone... but is easily rubbed off completely. I can say that the hardness is similar on both the agate and the browns..... (probably why it was so beautifully river tumbled!)
