Although this novella stands out from his body of work in that it’s a playful yet sinister fairy tale, it brilliantly fuses F. Scott Fitzgerald’s ongoing lush fantasies about the extremes of wealth with his much more somber understanding of what underpins it.  Loosely inspired by a summer he spent as a teenager working on a ranch in Montana, The Diamond as Big as the Ritz is Fitzgerald’s hallucinatory paean to the American West and all its promises.
It’s the story of John T. Unger, a young Southerner who goes to Montana for summer vacation with a wealthy college classmate. But the classmate’s family proves to be much more than simply wealthy: They own a mountain made entirely of one solid diamond. And they’ve gone to dreadful lengths to conceal their secret … meaning John could be in danger.
But the family also has a daughter, lovely Kismine, and with her help, John may yet escape the fate her family has meted out to all their other guests so far …
