It looks like what is known as red "plume" agate. There's a lot of it in Texas (notably Woodward Ranch) and the west of the state in general. I guess it also occurs in Arizona but if not it's certainly pretty enough to be transported or traded isn't it? The branches are natural mineral deposits.

You're welcome. I just googled it too and there seems to be a place in Arizona called "Bloody Basin" where material like that occurs and is named after the locality. Don't know if that is anywhere near you.

  Sorry, I misread that you found it in Colorado... I had Arizona in my head. This may be nearer?
