Break Your Own Geode Random Pull Rough! This listing is for decent sized (baseball to softball sized) Moroccan Geode! Moroccan Geodes have a very high rate of stunning crystals within, most often quartz based, but sometimes even Amethyst! Each one has been hand selected by our experts to provide a near 100% hidden crystal cavern rate! We are so sure of these, if there are no crystals, simply send us a photo of it broken and without stunning crystals, and we'll send your money back, or a replacement; whichever you prefer! Geodes form from lava cooling and creating pockets; generally from the evaporation of water rich soils. Once these cool, mineral rich waters pour into the hollow openings, slowly forming the stunning crystals you can find!
