Larger View

These whole, unopened geodes are an exciting addition to any earth science, geology or rock & mineral unit. Sorted by density, they are nearly all hollow and can be easily split open, using an ordinary hammer, to reveal a variety of crystal formations within. Students love opening these, then trading the pieces to begin their own rock collections. Our favorite way to split them is to put one in an old sock, then strike it with a hammer outside. This keeps all the pieces together while protecting bystanders from any fragments. Remember to wear your safety goggles. Sold in packages of 6.

Geodes Slices

Set of six slices of highly polished geodes. You can clearly see each layer of the different minerals.

Petrified Wood

Rocks with Windows

These ordinary looking rocks are made of quartz and have a polished side which allows you to see inside.

Small Geodes

Beautiful 1 to 2 inch (2.5 cm to 5.0 cm) geodes, cut open and polished.
