Its deep red to a khaki to black with a red glasslike film over parts. I'm sorry for the weak description and even worse pictures. The phone camera is pretty cruddy. I'm guessing red rhodium?

Hard to tell by photos, but looks possibly more like
Mahogany Obsidian to me. Really pretty stuff and if it is, the darker spots will be translucent.
Here is a cabachon I made from some......

OMG that's it!!! You're so wonderful! The polished sample you linked to was almost an exact match, but much prettier! Your cabachon is gorgeous!

Here is a picture of a Mahogony Obsidian arrowhead that Phil NM made and donated for raising rally funds in 04'.
Quoting Phil......

Really like the look of that obsidian - the uncut and the worked both. I'll have to keep my eyes open when I'm out this year.

Are you referring to mine? It's wet to attempt to show the color (camera failed me). if we ever meet you can have it!

Yes, and thank you, but no - you should do something with it, it looks very cool. I am going to try to make the spring outing - perhaps we could meet there, with the rest.
I made one of those last year, and it was a blast!

Well unfortunately there is nothing I can do with it. I don't have any tools. Maybe I'll give it to Mrs.P to work her magic on if it really is mahogany obsidian. Maybe she can make a awesome piece for the club treasure ches. I just thought it looked cool in the river. The clear red layer looked like a fossil when I pulled it out. I'll look for more the next time I'm in my hidey-hole!

Ask Mrs P about the equipment needed to work stones.... I am sure she would be glad to give you advice.

You can just call me D or Denise.
....... Just don't call me late for the chocolate.
If you want you can send it and I will see what I can do with it. Not sure about size or fractures by the picture but I will do my best.
PM coming at you fenixsmom.

Kind of hard to tell from the picture but it looks like it may be a chuck of petrified wood, we have collected a bunch from the creek (the kids have any way), polished up they look great.

yes that picture is kind of vauge. Can't really tell if that is Quartz or Microcline, Light Green or Sky Blue?
If that color is light green, well I'd say it was microcline with a weak showing of Amazonite. If that color tint is Sky Blue than I would suggest it is Quartz. Blue is one of the natural color varriaties of Quartz.
If I had to hazzard a guess I would say Blue Quartz. Woody

I think you could be describing what might be Epidote but the picture you are showing looks like a cobble stone....possibly Jasper?
Definitely not Amazonite from what I see. Always hard to tell from just a picture, you do a hardness test on it yet?

no i have not. dont know how
Hi Goldchef,
You'll see two threads for both Mohs hardness and mineral id'ing in this forum section pinned at the top. That should help narrow down the possibilities some what.
Personally I didn't see any blue or green hue to this rock......looks like a piece of quartz to my eye in the picture.
