What is a Geode?

Geodes are formed from fluids which crystallize in cavities within a rounded rock or nodule. Geodes are found in many parts of the world. The geodes contained in this set are from Mexico; 90% of them have hollow centers lined with crystals. Break open yours and look for the hidden crystals!

How to Break Open Your Geodes

Put the geode in a bag or sock. Hit it firmly with a hammer, aiming for the center - safety glasses and adult supervision are recommended.

Customer Reviews


5 star rating  Awesome geodes
Aaron M from Dallas,TX
Most all are hollow with quartz.A few are crystalline and I have gotten moss agate filled ones.They are a great way to get young rockhounds started on their collection.My Grandfather got me started in rock collecting many years ago.Highly recommend.

5 star rating  To show what is it on the exterior
Martin from Quebec Canada
i own many geodes that are already in half polished or not, those are to show what they look like when you find them in nature, is it a fossil, an odd looking rock, a piece of petrified animal or what?

5 star rating  Great fun!
Roland Thomas from Cleveland, Ohio
I bought these for my sons classroom, the students loved smashing them open to discover the gems inside.
