I know I’m straying from turquoise, but bear with me. Best I could do rockwise. Don’t really have any idea what these are, but really liked them (beaches are full of them).
Lake Superior is known for its agates, but I don’t know that that’s what these are.They would look cool set with turquoise!
Bottom, charcoal one is amygdule Basalt. Reddish one with stripes could be banded iron.
I saw that basalt is one of the rocks in Lake Superior. After looking some stuff up, I’m thinking a couple of those that are banded are agates. But you know more about rocks than I do! I’ll Google those. Thanks!
I do not see any agates in your photo.
Thanks! I’m not very familiar with them. I’m wondering if the top right is what is called a pudding stone. I read that they are a conglomerate. It also has a band of crystal type stuff in a crack. I really don’t know much about rocks other than turquoise LOL. Although I certainly spent a lot of time as a child picking them up while on the Great Lakes.
