“‘Down there,’ said Golg, ‘I could show you real gold, real silver, real diamonds.’

“‘Bosh!’ said Jill rudely. ‘As if we didn't know that we're below the deepest mines even here.’

Down in Bism we have them alive and growing. There I'll pick you bunches of rubies that you can eat and squeeze you a cup full of diamond-juice. You won't care much about fingering the cold, dead treasures of your shallow mines after you have tasted the live ones of Bism.’”
— C.S.Lewis, “The Chronicles of Narnia: The Silver Chair”, Chapter 14, “The Bottom of the World”
