Soak the geod in a glass of water, see if it turns murky. I have never heard of a natural crystal rock (geod) being harmful in water to fish or etc. It may be pretty neat looking underwater with an aquarium light shinning on it. I have geod rocks lining a water pond full of goldfish... I have not had any fish die from the geod. I have seen the fish lay on or next to the geods looking pretty happy. summer.. |

Look up the art of lapidary (rock polishing). One uses a metal wheel that rotates horizontally and various grits (like sandpaper without the paper). Start with a coarse grit and use finer and finer grits until it gets shiny enough. |

The crystals in geodes are precipitated from water that infiltrates into the hollow cavity underground where the geode will form. Usually the crystals are made of quartz, a mineral which can precipitate directly from molten magma but can also be carried in solution in water underground, which is the case for geodes. The crystals start to grow on the surface of the cavity, and begin as many small ones. As time goes on and the crystals grow larger, some of them crowd out the slower growing ones around them. As this happens the ones that survive continue to get bigger, and because they are all growing toward the center of the geode, they will be larger toward the center because they have had longer time to grow in that direction. |
