Episode 7: Diamonds are Forever

You’ve heard the phrase “diamonds are forever.” But why did one specific stone come to represent love, commitment, and permanence?

In this episode, we trace how diamonds moved from rare status symbols to an expected part of engagement culture. We explore the role of De Beers, controlled supply, and the creation of social rules like the “two months’ salary” myth.

We also unpack the psychology behind diamond marketing, including scarcity bias, status signaling, sunk cost bias, and how price became synonymous with commitment. We look at the invention of the Four Cs, the impact of massive diamond discoveries, and how lab-grown diamonds are quietly disrupting a narrative that’s held for nearly a century.

This isn’t an anti-diamond episode. It’s a clarity episode. Because once you understand how something became “forever,” you get to decide what it actually means to you.
