In The Diamond as Big as the Ritz, wealth is portrayed as a corrosive influence that distorts morality, erodes empathy, and ultimately annihilates those who attempt to wield it without limit. The novella’s exaggerated premise—a mountain made entirely of diamond—allows exploration of the logical extreme of material abundance, revealing that excessive wealth actively reshapes ethical reasoning. As the Washington family’s fortune expands, it produces isolation, violence, and psychological detachment, culminating in the family’s destruction.

From the novel’s outset, wealth is an object of reverence rather than utility. John’s upbringing in Hades has taught him that riches command respect and humility, as “the simple piety prevalent in Hades has the earnest worship of and respect for riches as the first article of its creed” (98). This reverence primes him to accept extraordinary wealth as inherently meaningful. Yet the narrative quickly exposes the emptiness beneath this belief. The Washington estate overwhelms John into passivity; surrounded by sensory excess, he becomes physically inert as “jewels, fabrics, wines, and metals blurred before his eyes into a sweet mist” (102). Wealth here is anesthetizing, dulling perception and suppressing agency, as evidenced by John, who is quickly lulled to sleep during dinner as a result of the excess.

As the narrative progresses, it reveals its argument that extreme wealth requires moral destruction to sustain itself. Braddock Washington’s worldview exemplifies this shift. He openly rejects conventional ethics, asserting that “cruelty doesn’t exist where self-preservation is involved” (116). In this logic, maintaining wealth at all costs becomes synonymous with survival, granting exemption from moral accountability. Human beings—enslaved people, aviators, and guests alike—are reduced to obstacles or liabilities, their lives expendable in service of the preservation of wealth. This moral destruction extends to emotional and relational bonds as well. Kismine and Percy, raised within this system, demonstrate how affluence warps human connection. Kismine is capable of affection but rationalizes murder as “inevitable” when someone is a perceived threat to their wealth. Percy treats violence as mundane, laughing at danger and discomfort alike. Their emotional responses are shaped by a world in which consequence is consistently deferred, and the novella suggests that when wealth shields individuals from accountability, it erodes the moral feedback mechanisms that sustain empathy.

The culmination of wealth’s destructive power appears in Braddock Washington’s attempt to bribe God. By assuming that divine authority operates according to economic exchange—“God had His price” (133)—Braddock extends the logic of wealth beyond human systems into metaphysical absurdity. His belief that unlimited riches confer universal control above even God represents the final stage of moral collapse. When this bargain fails, he annihilates everything: the estate and all the people within it. The diamond mountain explodes, destroying both the Washington family and their attackers. The fortune that once promised invulnerability becomes the instrument of extinction, completing the novella’s argument about wealth as a source of destruction. In the novella’s aftermath, the estate’s ruins emphasize the fragility of material excess. The “house of jewels” dissolves into “a great featureless pile” of marble dust (136), leaving no legacy and illustrating the narrative’s assertion that wealth, when pursued without ethical constraint, is inherently self-consuming.
