Yes, need to post a pic. Very difficult to ID written descriptions of rocks. Even MORE difficult when there's not even a description!

Sorry bout that fellas

Sorry bout that fellas
Was found near other black chunks of same size obsidian but this was a little farther apart from the rest of the regular stuff

I'm thinking green obsidian or possibly Jade?

 

[123cherryb]

I just tried to weigh it.

Looks (to me) more like obsidian.

You say there was more obsidian found nearby? How far away? How much? Was anything else found there as well??

It is just green obsidian probably had sulfur around it when it formed there is all kinds, red with black spots black with white lines etc. Knappers may want it for arrowheads but your piece looks very cracked and shattered hard to break off smaller solid pieces. There is whole mountains of obsidian of all kinds and colors you will most likely get nothing for it sorry for the bad news.

There was volcanic activity history near by
and lots of small chips everywhere this was found a bit farther away than the same size chunks of black obsidian.

this is interesting to me,is it hard to show the green color,does it look black.im asking because my son gave me an arrowhead that his friend gave me because he knew i liked them.i kinda just put it away and laughed because he said it came from a cave somewhere and now you show this,im going to get it and take a pic.

I was just wondering if it couldn't have been slag glass rather than naturally occurring.

There is green obsidian on Glass Butte in Oregon, but the guy that found it is pretty tight lipped about the location. In other words, if you want some, you have to deal with him. Your sample actually looks prettier than the Glass Butte stuff, which is opaque, while yours appears to be translucent.

The high grade green obsidian comes from near Burns Oregon.
It is prized by knappers and rock hounders, but available and not too expensive.

Maybe $4 a pound, as a ball park figure. High grade stuff

Average obsidian with flaws and cracks can be had as low as 50 cents to a dollar per pound, such as you have.
Usually people want obsidian that can be spalled or sawed without falling apart.

Did you know there are over 200 varieties of obsidian ?
Many odd colors and sheens and high grade rainbows that will knock your socks off.

Possible you might find someone such as a facetor that could make a pretty stone for jewelry out of this ... or a cabochon is another possibility.

I'm just guessing, but that point has the look of modern points made in Mexico and long distributed amongst tourists.
If you're seeing green in it that would confirm my suspicions even more. It's hard to say.

Keep looking for those oddities and color variances ... you never know.
Obsidian is way cooler than most people are aware.

Snapped a couple quick ones to whet your appetite.
From Oregon and N. California.

My first thought was slag as well. We used to find big chunks of what looks just like near an old furnace area up the mountains.
