I never liked the idea of paying for diamonds, but what sealed the matter for me was how much my wife loved the lab diamond ring I bought her; 20% of the price of a natural diamond and indistinguishable from one without specialized equipment.
The price of diamonds will tank over time more so than it has already.
Sarcasm, obviously. I never understood why people prefer diamonds produced by the manual labor (and often suffering) of other humans over diamonds produced by the ingenuity and knowledge of other humans. Science, bitch!
Why do Michelin star restaurants cost so much when there's hungry children in developed countries? Why does finance and adtech pay so much when there's a shortage of teachers? Why is so much engineering effort and materials spent on luxury goods when infrastructure is crumbling? Why are five star hotels so expensive when there's a shortage of care workers for old people?
This is downright silly and wrong. Diamonds are not expensive because they're a cut above other gems, they're literally only expensive because of a monopoly that upholds artificial scarcity. Michelin star restaurants are expensive because they do culinary arts on the highest level. Diamonds are expensive only because one family owns all the mines.
Only if that answer is "the world is incredibly complicated and each individual situation is laden with its own history, nuance, and complications." Because otherwise: no, the answer to all those questions is very different, because the world is incredibly complicated and each individual situation is laden with its own history, nuance, and complications. It's reasonable to ask about what those particular nuances are for a given situation without being brushed off like this.
Diamonds are artificially scarce anyway. The big producers stockpile their output to keep prices high, and spread FUD about dirt cheap, just-as-good synthetics.
Why is it diamonds, and not iridium, pearl, or opal? Why does a diamond's value depreciate to nothing the instant it's sold, unlike gold? Why did the price of diamonds shoot up so drastically in the early 1900s? Why are the indistinguishable lab-grown diamonds in so much lower demand? Who are the major actors in the diamond trade, and what are their strategies and relationships to one another?
Many books could be (and, I'm sure, have been) written on these subjects. Don't act like "Econ 101" explains everything. "Econ 101" introduces a bunch of extremely simplified models that are later qualified, criticized, complexified, or even outright replaced. That's all fine if you're continuing on to get your economics degree, but I'd argue that someone who took Econ 101 without continuing into much more depths in economics probably has a worse understanding of the world than someone who never took it, because they take these ridiculously over-simplified models as some sort of inalienable truth. After Econ 101 you merely "know enough to be dangerous(ly wrong)".
