After a single quartz crystal has grown, if silica is supplied again, such as by allowing time to pass, it may incorporate the original crystal as if swallowing it. Such a state is called quartz-in-quartz, or sometimes "nested quartz." Compared to ordinary quartz, its rarity is overwhelmingly increased because it requires two stages of formation. Also, incorporating another crystal means that the possibility of cloudiness also increases, so it is precious to have this clear state polished as a loose stone.
