These 3 rocks took an extra good shine in my last batch and I'd like to learn more about them. Can anyone ID them? Thanks...

No idea but they sure are nice and shiny. Could be some type of jasper.

I would say jasper as well. The top two look like the butterscotch jasper and opal I find from Central Nevada.

If light in weight, I've seen some Tagua nut (and similar vegetable ivory) with similar creamy colors. Another possibility would be feldspar (easily scratched by jasper). If heavier, the piece on the right looks like it might have a dendrite formation, so that one would probably be jasper or opal (as well as the 2 on the left, which others have already responded).

Thanks...interesting possibilities I'll read up on for sure as I like to learn new stuff. None of them feel light (in hand) and seeing as I found these river tumbled at the local river here in southern Alberta Canada I'm doubting if it's Tagua Nut? Vegetable ivory...is that what a Tagua nut would turn into after a few centuries? Like petrified wood kinda thing?

Ok not centuries...more like no more than a year according to the link below: www.ecuadorianhands.com/blog-en/2013/06/ten-truths-about-tagua-vegetable-ivory/

Vegetable ivory...is that what a Tagua nut would turn into after a few centuries? Like petrified wood kinda thing? Then not Tagua or other nut ivory. Those are organic gem materials (like pearl), and I'm not aware of fossil forms. Not light weight also would rule out amber. Tough to say for certain from photos, and your area has a lot of glaciation that can move things far from their origin. If you have any unpolished pieces, you might start with a scratch test to narrow things down.

Since my tumbling success with the photo rocks I've been rock hounding similar stuff and will definitely do the scratch test...

Just my opinion, but they look like "Butterscotch" jasper.. We have a lot of it around here...

I did the scratch test and a steel file didn't noticeably scratch it so between that and the majority responses saying it's jasper that's what I'll say it is...and "Butterscotch" is as good a name as any so that's what I'll call it also. And bonus there's lots of it around here too...just never paid any attention to it cause it looked too boring when rock hounding (slowly learning not to judge a book by it's cover:) ) Anyways finally something around here that'll shine up nice other than quartz! Thanks for all for your responses...it is appreciated!

Thanks...more info to file away in the Butterscotch Jasper folder in my brain! What you're holding looks a lot different than the river tumbled Butterscotch Jasper (as I'm calling it) I'm finding. I've often wondered without really thinking about it why there are so many smaller, roundish rocks out in the middle of nowhere in this dry prairie area and now I'm understanding more and more what rocks2dust said upthread about this being a glaciated area and how rocks got here. Our local river comes from the Rocky Mountains about 4 hours away and over the centuries I guess new stuff is coming all the time. My river rock hounding trips are going to get more interesting I'm thinking

I have some "Butterscotch" jasper from the rivers around here also...I'll see if I can remember to get a photo of a few...
