I got this rock from my grandfather's estate and started cutting it, have searched through tons of online info and can't ID it... Can anyone here help me out? Thank you! Attachments:

Strange stone - Geologically speaking it's pretty dang cool! That poor stone has been through hell and back! The only thing it brings to mind is youngite, but your stone has a much different look to it.
Nice score though!

Looks like a ribbon type jasper that has gone through some major stress early in its formation. The bands on the right in the top pic would be the most recent to be laid down, and would be the top layers. The earlier layers were fractured by a strong earthquake or other land shift. Very interesting piece. Don

Thank you both for your responses! I also thought it was a type of jasper, but haven't seen anything like it. Really appreciate the geological explanations as to it's interesting formation.

Hardness? Are there soft bands amongst those?

I don't have a way to test hardnes sat this time, it seems to be about the same hardness throughout. There are many small druzy areas throughout each slab I cut.

Where was your grandfather's estate located?
Did he self-collect mostly or was he a dealer gathering material from a great many sources?
General location might bring a clue.

That's a great question. He was from Oregon, most material was self collected and mostly in Oregon, but I know he also went to Idaho, California, Arizona, Nevada, Washington, and did occasionally buy some stuff...sorry don't have more specifics, but the vast majority of his stuff is from Oregon.

Found it!!!!
In Agates II by Zenz, page 204, there is a picture of 'jasp-agate' that is almost exactly the same.
It says that the piece comes from Eagle Rock, near Prineville, Oregon.
Anybody else with the book, can you verify what I am seeing?
(And may I use your photo in the Agate Index for Oregon?)
