GEODES FOR SALE

Geodes are hollow, often rounded voids in rocks filled with crystals and other minerals. They typically form when gas bubbles form hollow cavities inside cooling volcanic rocks. Over time, mineral-rich water seeps into the rock, depositing tiny crystals on the sides these hollow cavities, which gradually build into visible crystals. This process can take millions of years. We carry geodes from many locations, some of them containing spectacular crystal formations.
