Strangely, it almost looks like a Calcite crystal inside. I'm not sure, but it's awesome! Great job! -Luke

Excellent job. I have a couple geodes and a wet tile saw but don't know how to choose where to cut. Do you weigh it or go by external features or just go for it and hope for the best? Nice.

There is a place close to Hamilton Illinois right across the Mississippi river from Keokuk Iowa where you can dig geodes for a fee. I think it was around twenty five dollars and we dug three five gallon buckets of them. I've been putting them in my Geocache off and on for several years. Look up the Big Kahuna in Wisconsin.

Calcite comes to my mind as well, if you can get your hands on a short wave black light it might fluoresce if it is calcite. Take a look at my busted geode post I made and you'll see what I mean.

I use the SWAG method. Scientific wild a$$ guess.

There is a member here with a post titled "Need a rock identified?" or something close to that. Do a search at the top right of the page and it should come up. Cool find whatever ya call it. Good luck.

None of the geodes we open had anything fantastic inside for crystals but it was interesting to the wife, kid and myself as well. We had to cross a small creek to get to the dig site and I happened to see a round rock laying in the creek so I picked it up and gave it a shake and sure enough it was a geode and hollow inside. Check out the site below.

Good luck,

Isn't the simple test for calcite crystal, a drop of muriatic acid? If it bubbles, good chance it is calcite. I have seen people do this in the field on native rock to confirm calcite, but never seen it done on a geode.

Actually bubbles indicate a carbonate but it is a valuable test. Even a weak acid like vinegar will get a reaction on some. I dilute the acid to about 1/3 with water. Keep it off the fingers.

In cases where a natural acid acting on say limestone can have the affect over time of reducing the reaction to no reaction. I was at a mine once and the owner told of that being the case there.
Lots of geodes have quartz inside. Some purple amethyst.
