#4 - #7 i would call agate/jasper blends, i don't know the origin. #8, #15 and #17 i would call gold moss agates, #9 and #10 are marcasite, #11 is a chrysocolla/cuprite mix, #13 is mahogany obsidian. That's all I got.

Not all rocks have varietal names, because they come from areas that are unexploited or unappreciated from a lapidary point of view. Hence they have to remain "brecciated red jasper" or something similar. We often stumble on identifiable material, but looking like does not make it so unless everyone wants to believe.

Thanks for the help Not all rocks have varietal names, because they come from areas that are unexploited or unappreciated from a lapidary point of view. Hence they have to remain "brecciated red jasper" or something similar. We often stumble on identifiable material, but looking like does not make it so unless everyone wants to believe. yeah i get that, and when i have nothing else i fall back to the standard descriptive names. but with materials i acquire like this i try to ID if there is one in order to keep my prices on the reasonable end of the spectrum for my customers.

OK, some suggestions...
1) I'd agree with Sheep's Bridge sagenite. 2) Moss agate, but doesn't look like Maury Mt. to me. 3) Looks like Moss agate in jasperized matrix. 4) Looks like some central California coast agates I've seen. 5) no idea 6) I think I have a piece of something close to that somewhere (maybe Sonora Plume or Brenda Plume?) 7) No guess. 8) Nice moss. Mitchellite/Jumpin Jeep Moss and Maury Mt. Moss sometimes have brecciation like in yours. 9 and 10) Look like some Josephinite I've had. 11) Chrysocolla/cuprite mix for sure. Likely from northern Mexico, just based on the amount of stuff from there with the red cuprite. 12) From the creamy texture of the nodules, I can't get out of my mind that this resembles some of the datolite clusters I've seen from Michigan. If so, it is a fabulous piece. That said, I've also seen some jasper thundereggs from White Fir Springs with multiple jasper-filled chambers (again, if so, yours is exceptional). Richardson's opal bed and Rainforest jasper can also have the clustered nodules, but usually also far more matrix. 13) That pattern of mahogany with spots is sometimes called "Leopard" obsidian. 14) Looks very much like a thunderegg. Not one with which I'm familiar, but if you want to sift through the hundreds of named types, try to match the rhyolite shell, rather than the agate chamber. The shells, not the agate patterns, are diagnostic. 15) Several possibilities, but none close to satisfying. 16 and 17) Both remind me of "Gold Leaf" jasper/agate from Mexico. 18) Reminds me of "Crayola jasper" from Nevada. 19) Ringing no bells.

It looks like you have several materials from west Texas #15 and #8 are without a doubt golden moss agate from west Texas #6 and #7 are both red plume agate from west Texas #13 is mahogany obsidian I don't know about other places but this formation is common in the mahogany obsidian found near Alpine Texas mikethecabaddict
