Mexican Coconut Geodes
Our Mexican Coconut Geodes come from Chihuahua, Mexico.
Geodes are formed in gaseous bubbles in volcanic lavas. Minerals in solution within the cavity start to crystallize in layers as the surrounding rock cools. This usually forms concentric layers from the outside in, although, sometimes, when the process ends, there will be a non-concentric layer on the bottom of the geode that almost looks like it "froze" in place, and will have a flat bottom parallel to the ground surface at the time of cooling.
The type of crystal that forms inside a geode is determined by the composition of the hydrothermal fluids within the cavity, and in the In the case of the coconut geodes, it's hard to predict what formations will be inside, but the mineral composition will be mostly chalcedony with a chance for calcite crystals as you approach the centers of the geodes. Colors can vary from white to blue, brown to golden, gray to even red.
Geodes are so much fun to break open. It’s a surprise each time!
