colorful but what the heck. I find pieces of this fairly frequently in all colors, seems to be rhyolite which swirled with the quartz- soapstone-ish stuff and has pockets and layers in some, thoroughly swirled and blended in other areas...sort of streamed out and blended in some places and not others. The brown and black one has pockets of red and yellow showing flecks of it through the surface, I think if it was cut there would be pools of the soapstone/quartz stuff in it too. I suspect this will be too soft to polish, or too varied in texture, I've gotta get somebody to cut it and try.... volunteers? then i'll know if I should keep picking it up or not.

How hard is it? Soapstone is 1 and quartz is 7 so that would be quite a mix. I would love to check it out but I have so many projects going right now I can not seem to finish even one of them. Pretty interesting stuff. Jim

Cool rocks! The bottom green one looks a lot like a rock that I find. We have banded green rocks that seem to range from hard all the way to malleable with your hands. I've been trying to tumble them but many fail and come out of the tumbler more beat up than when I put them in, like this sad guy:

yes, looks much the same... quartz/soapy looking rock mixed with what I have taken to be rhyolite or basaltic stuff maybe... I need to get out the stuff and do a scratch test...report soon.

harder than copper penny,which left a streak but no scratch, softer than my steel pen knife which did leave a scratch... so that puts it in the 4-5 hardness range...
