Unbroken Geode
Unbroken Geode
Item #250
Geodes are hollow rocks that often contain mineral formations.
As with many geological formations, geodes often start with volcanic activity. But the geode is not formed by the volcano itself, but rather a void that it leaves behind.
When lava cools, it often contain air pockets. After the surrounding material hardens into rock, mineral-rich groundwater slowly feeds silicas into the void where they are deposited, little by little, over eons. Since these mineral deposits are often homogeneous, crystalline structures are allowed to form. As the surrounding bedrock erodes, the geode is freed from its formation strata.
Many geodes contain quartz crystals, but there is a small chance they could contain another crystal type. There is no way of knowing until they are opened. The contents and structures in a geode are entirely unique and have never been seen by anyone until you break it open.
To break open a geode we recommend putting it in a bag to contain any flying debris and hitting it with a hammer. Be sure to wear safety glasses just in case!
Small and medium geodes in the bag are approximately 1"-2"
