(I apologize for the humongous photos - I tried and tried but was not able to get them downsized either on my computer or using photobucket's tools. Don't know what the problem is.) I might have asked about one of these before, but darned if I can find it now, so please bear with me. This first is a very pretty dark green and shades of brown/tan with very solid areas bordered by softer, pitted areas. It seems to be around MOH's 6-7, but it also falls apart along the borders between the greens and browns. I thought maybe bloodstone, but I don't see the little red dots. This is a nice little hard, solid nodule. It has a very thin, reddish-brown rind, and the inside is a green that is so dark that it looks black until the light hits it just right. It has very thin red veins, but it's very solid. It's not obsidian - it's very dull, flat colored with none of the glassy shine or breakage, and no glassy "ting" when dropped. And lastly, a quite colorful chunck of some kind of conglomerate. I feel like it probably has a real name, I just don't know what it is. Any help with ID's on these would be appreciated. Thanks! Tom

Tom: The last one appears to be a pale example of Stone Canyon or maybe Trinidad Jasper but those brecciated types extend from Ventura county in the south to almost the Oregon border in Franciscan Formation cherts. Pale examples are very common in the fields around Creston, CA. I used to have access to a ranch where quite a bit was found so Lowell may have scored a few pieces I collected when he raided my yard before I moved....Mel

I agree the first one has a bloodstone sorta look , i`m leaning toward metamorphic greenschist , last one looks to be the metamorphic greenstone .

Thanks for the help! Now if I could only plug another quarter into my head and extend my memory a few more years ... Tom
