Apologies; I just looked up Stone Agates: hadn't heard of them until now. The ones I have do show facets that can be seen under bright light with a magnifying glass; faint but clear. Would machine-made agates have facets like that? This one is 3/4", with a small "impact crater" in one spot:

Thx. Is "Stone" the manufacturer?

Last week, I opened a box to discover my father's marbles, from when he was a boy in the 1930's. Since then, I've spent quite a bit of time online, learning all about marbles - had no idea - I was immediately captivated by how beautiful some of these are. I've been able to ID quite a few from online sources, but others are still a mystery. So I hope you'll indulge my "please ID these marbles" request, and help me out with any information you might have. I'm debating whether to sell or not - they're kind of cool -, but if there's any that are particularly rare or desired, I think that would be important to know. I know there are a lot in these photos; there were over 100 marbles in the box. . .. Thanks to all. All are roughly 5/8", except the 2nd image, which are 1", the 3rd image (3/4")and the last image where 1 is around 7/8"and the other two sized in comparison
