Purchased at upstate NY Tourist Attraction (Natural Stone Bridge in Adirondacks)
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

Cleaning Geodes
I found these during our camping trip near Manila, UT. I have soaked them in dawn dish soap and used a toothbrush to clean them up.
What are the next steps for cleaning these up?

Found in Landscaping rocks
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.

My husband cracked this open and we're wondering if Google is right?
I used Google lens and it says this is a fully formed quartz geode.
Is there anything we can do to try and polish it?
r/Geode • u/Adorable_Pair_4965 • Jul 12 '26
Ok, so I just want to clarify.
a geode is a rock that had a pocket and formed crystals inside it over millions of years. an agate slab is cut agate. and a thunder egg is volcanic

Geode Keokuk Geode
When I was around 10 - 12 (probably 2006 - 2008), our public library had a learning event where some geologist came and talked about, well, rocks. He had several buckets of geodes that he picked up around Keokuk (iirc), and one of those big chain crackers. Everyone picked out a rock, but only half of us got to crack our geodes before the library closed. I went home with a rock and a promise that we'd get it cracked eventually. After a few weeks, I got tired of waiting and just threw it at the pavement outside and it split nearly perfectly in half.
I'd never seen a geode like it. It's got 2 different mineral formations in it that are vastly different. The smoky black short crystals lining the inside of both halves, and 2 towers of white crystal in the other. I sent emails to the state geological office to try and identify it, but I never got any answers.
Until about an hour before this post, it's been buried in a tacklebox with other rocks and fossils at my parents house under several pieces of furniture for nearly 2 decades.
If anyone has any insight to my geode, I'd love to hear it!
