\Usually geodes (or their counterparts, nodules) can be identified by their shape, weight and texture. Many geodes are round or oblong and somewhat heavy for their size. The outside of a geode or nodule is usually worn down and resembles a head of cauliflower. Many geode crusts are limestone and may have a dull tan or brown coloration. But as for actually knowing if it is a geode by just looking, it is a probably a 70 percent chance of being correct.

It is a geode. Geodes form in gas bubbles in cooled porous lava flows. Groundwater provides the minerals that crystallize inside these hollow bubbles. Eventually erosion removes the lava rock that provided the mold that shaped the outside of the geode and then humans find them (and usually cut or crack them open to look at the crystals inside).
