Cleavage is the degree of deformation that occurs with types of rocks. The cleavage of geodes is indiscernible due to the irregularity of the stone.
A geode with a flint in it is called a "nodule".
I think you are describing a geode. They are generaly hollow and crystalline in structure

The only way for the average person to tell if a rock is a geode is to crack or saw it open and have a peek inside. Experienced geode hunters will recognize characteristics in the appearance of its exterior, or perhaps notice that it appears to be lighter in weight than similarly sized rocks, indicating that a partial cavity may still exist inside.
