JD-
Cool little dudes you've got there. Some of those with the quartzy veins on brown could possibly be petrified wood. Hard to tell from a small pict though. That little one at the bottom with the "white measles" looks like some sort of conglomerate.
I'd say roll 'em and see,
gaeter
PS..........where ya from?

Dang-
I think you could do some pretty good damage in all the bays and islands that surround you. I'd be for spending some days on the beach and possibly some inlets. I think you'll find more than you can handle.
Before you drop good money on ebay, take the kids to beach and enjoy the outdoors and collect some local rocks.
Good luck,
gaetz

I'd just throw them in the tumbler and see what happens. They look like they're halfway tumbled already.

A couple of the lighter colored ones look like one I broke up and tumbled and they turned out really neat.

Pretty hard to id from pics for most of us. One thing you could do is some searches for local WA stones or things like that. You might find something from a university or something. Another thing is to check for a local extension office or rock club in your area. They might have someone who could help you id them.

The top two look like they contain quartz but the bottom two are mysterious to me. Have you tried a scratch test to determine hardness? That could tell you a lot.

Ok, look at the MOH chart at www.amfed.org/t_mohs.htmEach of the materials at the bottom of the page can be used to try to scratch rock. Also rocks of a known hardness such as quartz (MOH 7) can be used to scratch unknown rock. Try the copper coin first. Give the rock a good HARD scratch. Look at the scratch with a magnifier. (I like 10x) You will see that the copper did NOT scratch the rock and that the rock has a copper streak on it where the copper wore off. The copper was scratched, not the rock. Now try scratching the rock with a knife blade. Do NOT use a knife you like as this will ruin the blade. Pick out a sacrificial cheap knife and use it. Do not use a Swiss army knife. The steel on those things is harder than a cheap knife and will throw off the test results. If you can successfully scratch the rock than the rock is 5 to 6 on the MOH scale. Maybe a feldspar. Get a quartz crystal. Use it to perform the test. Quartz will scratch other quartz. This is not the most exact test in the world but with a few items to scratch with you can get a general idea of the hardness of a rock. This may not be too clear but I hope it helps. |

The bottom 2 pics remind me of picasso jasper. (I think that's what it's called) However, I was expecting it to be hard and it's not...it seems fairly soft.
Is that material soft? I've got some that has black , grey and brown in it and am struggling to get a glass shine.
So far, I've been able to get a very nice satin finish....which isn't all bad. (Not tumbled though...but machine polished)

I don't know what it is, but I've picked up a ton of it here and there. Sometimes it shines, sometimes it has beautiful patterns and is heartbreaking because it never shines. Yours looks promising, especially in the last pictures. It never hurts to toss them in a barrel and find out, you get some nice surprises that way.
