Identification Help?

[02heatherness]

I would love to know exactly what these are. I think some of them are agates. Any help would be so appreciated thanks!

Bottom pink ones are definitely dyed agate. They are typically sold in many sizes from small up to uber large for jewellery making. They're quite easy to find.

I don't know about the others - somehow they don't look "real" if that makes sense? Of course ID'ing anything from a photo is almost impossible (unless, like the one above, it's incredibly obvious)!

I would hazard agates too but I think the pink ones have been treated. I do not know if the rest are treated or not.
