Quartz crystal (頗梨): lisi [fanqie]; sphaṭika; translated here as "water essence" (rock crystal), also called "water jade", or called "white pearl". In the Da zhidu lun: this jewel is produced in the crags of rocky mountains. One theory says that ice turns into it after more than a thousand years; this statement is unfounded, for the western lands are sweltering and hot without ice, yet are abundant in this jewel—what could have transformed into it? This is merely a type of stone, found everywhere.
