cloverdale is known for obsidian samples like that.The native americans treasured it for its workability for tools.there are many colors known.

There is a rock/fossil thread on here.. Could try posting in that if you can't get answer here. Have no idea what it is but I know I have seen these type rocks before in stores and stuff.

 

[BRATTSO]

sure i will try that thank you

I think it looks more like it could be a gemstone than a rock!

If it is an amethyst, Koolaid, it couldn't be more than 2" across at most. Not too many amethyst crystals larger than that. I vote a variety of obsidian.

 

[BRATTSO]

I have heard both obsidian but most say amethyst its about the size of a softball a little larger

 

[koolaidsmile]

Actually it could be a gemstone called ammonite which has purple and black mixed in it with a bit of other colors many times too!

The only amethyst deposit in California I have heard of is in Shaver Lake and it is underwater in the lake so I don,t believe it is amethyst.Probably obsidian.

Or it also could def be rainbow obsidian!!

[koolaidsmile]

Examining it from what I can see in the colors I'm def leaning to rainbow obsidian!!

Looks a lot like slag to me.

 

[BRATTSO]

I have checked out all the rocks and my rock looks like purple glass from what I see it looks most like an amethyst. It really doesn't look like obsidian

I will post pictures of it after taking it in sunlight

Thank You all

The river is near clearlake the biggest lake in california I believe. I Have heard it has many different kinds of crystals and some kind of knock off diamonds

Looks like glass. Big, recycled chunks as used in gardens and aquariums.

I agree with Charlie P. ... this looks to "broken and shinny" to have been dug from mother earth . So I'm stickin' along with Charlie P. and my visual ID is glass or Slag used to decorate aquariums and gardens ... in fact I think I have some in the garden now ... IMHO , Woodstock

Here are more pictures

You think its glass really?
iT does look like some different color stone is in it like a white boarder or a floating rock. I am taking photos with my notebook so they arent very good I cant find my cam

Thank you
