What's inside a geode?
The hollow interior often is nearly filled with inward-projecting crystals, new layers growing on top of old. The crystals are of quartz, less often of calcite or dolomite, and sometimes of aragonite, ankerite, hematite, magnetite, pyrite, chalcopyrite, and sphalerite.What is found inside geodes?
Most geodes contain clear quartz crystals, while others have purple amethyst crystals. Still others can have agate, chalcedony, or jasper banding or crystals such as calcite, dolomite, celestite, etc. There is no easy way of telling what the inside of a geode holds until it is cut open or broken apart.How much is a geode rock worth?
A geode can be worth anywhere from $5 to more than $1000, depending on its type and location.

Large amethyst geodes can go for thousands. Baseball sized geodes with non-spectacular quartz or calcite crystals can be purchased for $4-$12. Geodes with uncommon minerals that are sold on mineral auction sites range in price from $30-$500. Golf ball sized geodes, uncracked, are sold for about $2 at shows.”Do geodes have crystals inside?

Fake geodes can be identified based on how they were manufactured. Synthetic versions lack flaws that are found in natural geodes, while composites and imitations often have evidence of bubbling, cracking, splotchy paint, artificial color, and leftover glue.How were geodes formed?
Geodes are formed when there are pockets of air within rocks. This often happens after volcanic eruptions when lava cools around air bubbles. These pockets leave space for groundwater to seep in.
