I'm still processing the rock from my last fall hounding on a new river and the variety of chalcedony colours and patterns seems to be neverending. the largest peices are about 3x4 in. I am finding some nice blue which for want of better names to call it is "BC BLUE" and the range of colours goes from black through the greens and greys to a range of other colours and combinations. some of it is silified sedimentary deposites altered by subduction and volcanic activity, and all of it seems to be altered in some way by fracturing and healing, pressure/temperature variations, and silification at some point.

thanks they are a real solid jasp, rhodonite, hematite mix. I made my daughter a feng shui pyramid out of it which remids me; I need to let her know it's finished Attachments:

thanks; I just looked at the picture and it is one from the beginning of finishing with a 320 diamond lap finish and a quick coat of the sweat off my brow, or skin oil if you want to gross the girls out:<) i keep forgetting to put measurements in; it is to the same porportions as most of the pyramids round the world and stands about 2.5 inches

Nice finds, Lloyd!! Some of the patterns in the materials still remind me of Morrisonite. That's a rockin' pyramid you made for your daughter!!

thanks Ginge I don't want to load the site up with pictures but you should see the ones I cut yesterday; unbelievable colours and patterns in the morrisonite looking material ao I cut some 3/16 in slices tonight so you can see the translucency and see it is really a chalcedony type material. I put the pyramid together with grout I made from epoxy and the grinding dust after it dried out. It turned out really well considering it was all done by eye. the stuff is really hard to grind too because there is chalcedony mixed in there too; I get the occasional patch of the BC Blue even in the red.

aw what the heck, one more pic and that's it. most of the microfractures are filled but some of the larger ones even though they will stay together in sawing, I drop the stone on the bench to see where it will break because they don't go all the way through sometimes. I haven't tried epoxy filling any to save the large slabs but I think I will at some point if I want a big slab, this peice is 4 1/2 inches and the camera just won't capture the amazing brightness and varieties in the colours Attachments:
