Well , it looks like you have quartz agates / chalcedony - the one showing blue is nice , but I have no idea what it is - I would like to see some more pics of that one !

Thanks for your reply mate ! Yea i thought quartz just wondered how it got so round and bubbly.
Here is more or the blueish side of this .

I'd call it a chalcedony geode however the hollow may have just been a vug. Nice example If you get the chance try looking at it under short wave uv light.
Check out this link and the second paragraph in particular. https://www.minerals.net/mineral/chalcedony.aspx

I will have a read, thanks mate .

Get it "sliced" to bring out the vivid colors likely inside! TTC

Pics are coming in slow. I can see you had it cut. NICE. TTC

definitely try SW UV, it will probably fluoresce green from uranium salts (don't worry, not radioactive... )

they are all chalcedonies, the blue could be from included riebeckite or just a light scattering causing the tint, either way blue chalcedony is awesome

A little hard to tell from the photograph but the blue specimen could be Luna blue agate. Sometimes found around Luna New Mexico
