Why Are Diamonds More Expensive Than Water?
Water is simultaneously one of the few things we absolutely cannot live without, and one of the things we value least. Thereâ€™s an economic rationale behind that.
Cape Town has weathered three years of drought, and the city is rapidly approaching what theyâ€™ve labelled â€œDay Zeroâ€â€”the day the dams drop below 13% capacity, and the city switches its water supply off. This will force residents to collect their allotted 25 liters per day in person, watched by security forces.
Suddenly, Cape Town is realizing what many of us take for granted as we run water at full blast while washing our teeth, filling dishwashers daily, and hosing our cars down weekly. Water is simultaneously one of the few things we absolutely cannot live without, and one of the things we value least.
Economist Adam Smith famously posed the question, â€œWhy are diamonds more valuable than water?â€ He meant to highlight that diamonds, for all their cultural significance, are functionally useless. Writing for the American Water Works Association, marketing strategist and executive Melanie Goetz addressed this paradox.

The answer is a complicated phraseâ€”â€the law of diminishing marginal utilityâ€ â€”with a straightforward meaning. The greater the supply we have of something and the more we use it, the less we value it. We have oceans of water, pumped to many of us ceaselessly by the gallon. We have far fewer diamonds, hidden and embedded in rock. Their intrinsic value becomes secondary to the subjective value we assign them.
â€œEconomists tell us that the law of diminishing marginal utility dictates that consumers place a greater value on diamonds than on life-giving water. Itâ€™s just the way consumers prioritize priceâ€”by a productâ€™s â€˜least-value usage,’â€ writes Goetz, explaining that the lowest value usage of water is to clean gutters and sewer systems. Meanwhile, â€œwater may save your life in the desert, but even the lowliest of industrial diamonds carries a certain sexiness that invariably outstrips the redoubtable H2O.â€ She goes on to quote humorist P.J. Oâ€™Rourke: â€œâ€˜With an additional eight ounces of water, all we get is a trip to the bathroom in the middle of the night. With an additional eight ounces of gold, we get the upfront payment to lease a Lexus. Marginal utility explains why gold, vital to the life of no one except hip-hop performers and fiancÃ©s, is so high-priced.’â€
Yet, if Cape Town was now charging for water, its price per liter would be skyrocketing. As we plunge into a future of climate change and rapidly diminishing resources, it seems that many cities will soon be reconsidering how much we value those resources we need the most.
