You have amazing photography skills. If I could be half as good at that I would be quite happy with accomplishing that. I had an idea that with you great images, you could do searches on Google using the upload image function for ID (and do ask here as you have too).
That way you will find some like yours below and most all of them are already ID'ed for you. However, some people misidentify what they pictured for either deception, or they just don't know what they have. Go with the general consensus.
I TRIED to leave a link here where I used your top marble image but it did not work for the post but it worked for me doing it. They are Cat's Eye type. there are many different kinds of them so it narrows things down. Just an idea. Once you figure out the type, then study a bit about that type. It takes time and effort to learn about marbles but it is fun and worth your time.
