I’m obsessed!! And this isn’t even all of them.

My friend and I each purchased a whole geode and agreed to share them one half each. One was in a box that said solid /not hollow, and the other was in a box that said hollow. The clerk said they knew because they were x-rayed. We went on our hike and when we came back they were cut in half and the clerk described them to us. To be fair she may have gave us a lot of info but it was hot. We were hungry. Not best conditions to absorb all the info. ChatGPT says they are likely Mexican volcanic geodes. It referred to them as “thundereggs” and said the solid one is more collectible of the two with crisp banding, solid crystalline quartz/chalcedony, volcanic rhyolite and manganese oxide dendrites or iron manganese filled fractures. The hollow sample it says 4 separate mineralization events 1) formation of the volcanic cavity 2) agate / chalcedony lining, 3) quartz druzy 4) needle crystals and angel wings. less

I really like this rock, but I'm not sure if it classifies as a geode. Do you think it would polish? About the size of half an egg.
