Reviewed in the United States on 5 February 2017
I have sampled a few other geode-breaking brands and a lot of them were very hard to crack. Usually ones that are harder to crack are mostly rock and less cavelike crystal space. Only one of the rocks in this lot was hard to break, and that was because it was completely solid crystal. I'm not too upset about it because that's just the nature of geodes- sometimes you get a rock. 9/10 geodes is good enough for me.
Now, a problem is that even though there were many decent sized geodes, there were two that were pretty small. One was extremely small and seemed to have been under 1.5 inches in diameter.
Another thing is that about 6 of them were the same type of rock and looked exactly the same inside. I wasn't expecting a hand-picked assortment, but when over half of them are the same rock despite the varieties that exist, it seems a bit odd. Maybe I just got a bad lot.
But even still, the quality and overall easy-opening of these geodes compared to the other brands I've bought will keep me coming back for more every time I decide to start a new craft project.
