How to Identify Geodes
A geode is a round or oblong nodule with a bumpy, cauliflower-textured shell that feels noticeably light for its size — the hollow interior gives it away. Some rattle when shaken. Crack one open and the cavity is lined with inward-pointing quartz or calcite crystals; a solid, heavy nodule is more likely a concretion.
