Do geodes keep growing?
As water flows through the geode, additional mineral layers are deposited in its hollow interior. Over thousands of years, these layers of minerals build crystals that eventually fill the cavity. How long this takes depends on the size of the geode — the largest crystals can take a million years to grow.

What makes a rock a geode?
Geodes are spherical rocks that contain hollow cavities lined with crystals. In sedimentary rock, geodes might start out as animal burrows, mud deposits, or even tree roots. Over time, the air, mud, or tree roots create a hollow cavity within the rock, while the outer edges harden into a spherical shape.
Can crystals still grow?
No, you are right. They won’t continue to grow. They need to be kept in a supersaturated solution to grow. Solution means a lot, not just watery solution, they can grow in a melt or in a superheated “gas” (to hot to stay liquid not matter how high the pressure).
