Ok - one more from my online mine... Sorry for all the posts, but who doesn't like pretty rock pics ?
This one is about 3 pounds. There is reddish-brown grainy matrix still attached. The moss is red, orange and yellow ribbon on one end, and changes to filamentous moss in pink, cherry red, and white on the other end.
The matrix forms a white border where the agate starts.
First thought is it looks like a big thunder egg core - or maybe Maury mountain?
Thanks again!
