geode
This term describes a specific geological formation where the exterior is a plain, unremarkable stone, while the interior contains a hidden crystalline cavity. It evokes a sense of discovery and contrast between a rugged outer shell and a fragile, sparkling core.
In a scientific context, it is used precisely to distinguish these hollow nodules from solid mineral masses or veins. Because it refers to a discrete physical object, it follows standard English countability rules for tangible items.
