Hurry up and open the darn thing!!!
Geodes are my weakness ... I just love knowing that there is always gonna be a surprise when it gives!!!
One problem though .... I am having to learn not to murder the dam things. Some of the ones that I so impatiently cracked open were awesome beyond definition and I could only hope and tried to piece back together some of them.
Post pics please ... it feeds my habit!!!
As always .... Julie

Ooops .... missed the previous post!
Dam ..... love the hearts .... see I told you something cool would come out ... ;D
Wouldn't that be a real big kick in the head if a geode was cracked open and all these goodies spilled out ..... kinda like a real hard pinata!
As always Julie

we didn't have masking tape so scotch tape sufficed. we drew a line on top of that. It was helpful cause It gave line of reference as scoring this stone was in a blind spot Although I was surprised how easy the blade cut this rock as I was doing the cutting I thought to myself that I could just saw this stone in ½ Yep Chuck I got cold chisel technology Thanks for suggesting that I did start tapping around the rock Tas the neighbor turned & held the rock But he got impatient And said whack it so I did The results are in the pic above

I want to thank all for the nice comments on the hearts It didn't go unnoticed nor unappreciated I like the rock I busted open! A sedimentary lone roller that had lots of silicon quartz flakes in it. I guess, I would call it mica. Its flakes thin & is like aluminum foil and mirrorish. Plus it had a purple spot that was trying to grow. Who knows? Left alone for another thousands of years it might have grown into a geode. But this is a geode. The neighbor brought it over. Guess he bought it from the rock museum lousy pic... I'll correct that later the question is: I have thin kerf blade. Should I just saw it in half or score it and use the chisel method?

The old saw vs. crack debate. I have a bunch that I intend to saw because I hope to get some that are polish worthy. If you're not going to polish it, and if you have the patients, I would say crack it.
I don't think I would score it, though, so that you get a good fracture all the way through the stone. After seeing your pics, I think you could end up chipping the area where the chisel meets the stone and may even get a bad break there and end up having to try again in another spot.
It doesn't take long to crack them, maybe 5 minutes for a rock that size.
Hope that makes sense. Chuck

This geode is larger than a golf ball & smaller than a hard ball it also defective cause it already as a hairline crack in it! not sure you can see it in the photo? and would anyone like to try to I.D. the rock to the left of the geode? The green as a waxy lustre and I would say its about a 5 on the Mohs scale It scratches pretty easily and has 2 staples in it

Use the crack as your fracture line so you end up with only 2 pieces. Sorry if I'm stating the obvious.
No idea on the big rock, but I do wonder how it ended up with staples in it...

stating the obvious is good Hard Rock cause I can be dense- like a rock This was sweet. I scored it with a hack saw-just lightly & used my wood chisel on this fragile egg few taps and it snapped lots of growth and pretty crystals

here's what I found on my bar stool this morning i think the idea is for me to put an edge on that machete then crack some coconuts ! but I think these jodes may be really cool that blue, if it came out in the picture indicates something cool ! what do u think?

The big one looks like a beat up cannonball. No way to know if they're geodes without hefting them to see if they're light enough. Could very well be thundereggs. I would cut them rather than try to crack them.

Cannonball that's a good metaphor for this one, Chuck pretty sure there not jodes by the heft method plus,I have that other split one to compare it with here's a bit of a better pic how did it get round?

My understanding of thundereggs, and I may be wrong, is that the minerals get ejected into the air by a volcano and they cool enough to solidify. The air shapes them into spheres while they're molten. Thundereggs are also called "volcanic bombs". Here is an alternate theory: www.zianet.com/geodekid/thndregg.htmChuck
