	Ok so the bad news is I'm not ecactly sure where I found any them, more than likely somewhere in oregon or Washington. The first one is pale green on one side and black on the other. I don't even know how to describe the second one except that it's a few different shades of green and just has a lot going on. And the 3rd one is light reddish brown and black with white crack looking lines things throughout . Any help would be awesome! Thanks

	Well dm, I would guess your 2 green rocks are the same material. Might be some of the jade from that area. Look up Jade Cove and compare it to some of the stuff found there. The problem with these tumbled, rounded, and worn pieces is that it wears away all the signs and characteristics of the rock that normally help you to identify them. So you have to put them thru some tests. One being hardness. You can read about the Mohs Hardness Scale for rocks and some tests you can do to try and figure out the hardness of the rock. Another test would be figuring out the specific gravity of the piece. So, I am sorry to say, that all anyone can do by looking at a picture of these types of rocks is make a guess. The last piece might be some sort of agate or petrified wood, but that's just a guess, too. Sorry we can't be of more help.

	Yeah I'm usually at a beach or a river when I'm collecting rocks (mermaid thing) so most of them are pretty worn. I do know about the mohs hardness scale but nit about the gravity thing.....is there an easy way to test the fravity or do I need special equipment?

Here's a quick DIY video on how to get specific gravity using a scale.
