Today at a Glance:

  • De Beers created the modern diamond industry through the use of market manipulation, psychological hacks, and clever marketing.

  • At its height, De Beers had direct or indirect control of the majority of the global diamond supply chain, allowing it to wield its influence to manage prices.

  • “A Diamond is Forever” was the genius marketing campaign that created the diamond industry as we know it—convincing generations of men and women (1) that diamonds are a show of love—and that the size and quality of the diamond is proportional to the size and quality of the love and (2) that courtship and engagement involve a diamond.

  • Broad-based pushback against the industry and its roots has led to the rise of alternatives—like lab-grown diamonds—but diamonds remain the standard show of love in most Western cultures.


Diamonds Aren’t Forever

The mandate of this newsletter is simple: I explore my curiosity and share what I learn along the way. To be clear, this is an intentionally-broad mandate—I don’t believe that curiosity follows any fixed lesson plan.

The topics I will continue to cover include:

  • Growth and decision-making

  • Startups, investing, business, and finance

  • Writing and storytelling

  • Marketing

  • Life

The one constant across all of this: I can guarantee you will learn something new and interesting from each and every piece I share. One new idea or insight that will make you smarter or spark your curiosity to go deeper.

This is a learning-rich journey and I am fortunate to have almost 70,000 of you along for the ride. We’re just getting started.

This felt like a fitting preface to today’s piece. Why? Well, every now and then, a story comes along that grabs my attention and simply won’t let go until I write about it.

The story of De Beers and the making of the modern diamond industry is one of those stories. It stands out because it’s not a clear fit for any one of those buckets above—rather, it’s a fit for all of them!

So sit back, grab a coffee (or whiskey), and let’s go down this rabbit hole together…

The Beginnings

The story of De Beers starts well before the international giant existed.

It may be difficult to believe in the current context, but for most of history, diamonds were not a particularly important gem. Largely found in parts of India and Brazil, they were considered rare and beautiful, but had little intrinsic value due to their lack of industrial or monetary use cases. Diamonds were a vanity item of the ultra-ultra-rich—a very niche market.

But in 1870, everything began to change.

Massive diamond stores were discovered in South Africa near the Orange River, setting off the first diamond rush. South Africa was officially a British colony at the time, which meant that British investors immediately flocked to the region and commissioned labor—both forced and paid—to begin building the diamond mines.

It quickly became clear that the new South African mines would be producing never-before-seen quantities of diamonds.

The British investors grew worried. In a free market, the glut of supply—and associated dent in the perception of scarcity—would send the price of diamonds into free fall. Given diamonds did not have any major industrial use cases to buoy demand, the perception of scarcity was critical to their price and desirability.

So in 1888, one British financier and mining operator proposed a plan…

The Making of De Beers

Cecil Rhodes was born in England in 1853, but after a sickly adolescence marked by severe asthma, his father sent him to South Africa, a climate he believed would be better for his health.

Rhodes entered the diamond industry at age 18 in 1871 and began to systematically acquire and consolidate mining operations in South Africa. By 1888, he had built one of the most powerful mining operations in the region.

But the diamond industry was in turmoil, with wild price fluctuations and uneven demand. Sensing an opportunity, Cecil Rhodes and his business partners led a push to merge and consolidate the various South African mining companies.

His pitch: continued competition meant death; consolidation meant survival.

The new company—or cartel, as it were—was named De Beers Consolidated Mines, Ltd. Its explicit goal: to manage diamond production and continue to perpetuate the perception of scarcity and desirability that was so important to the price of the stones.

De Beers was officially born.

“A Diamond is Forever”

Econ 101 Lesson of the Day: There are two sides to every market—supply and demand. The story of De Beers is unique in its practical application of the manipulation of both…

Supply-Side Manipulation

In the 20th century, De Beers methodically expanded its influence over the entire diamond supply chain.

In addition to having direct control over diamond mining and production, it began to accumulate direct or indirect control of the major diamond trading companies across England, Switzerland, Israel, Belgium, Holland, and Portugal.

It was widely known and understood that De Beers controlled the diamond industry. With control over production and distribution, De Beers was able to control the stock and flow of diamonds in the market, effectively creating direct control over prices. While other commodities saw wild price swings, diamonds exhibited no such volatility, creeping steadily upwards over time.

But many cartels throughout history have managed to manipulate supply—demand is much more elusive beast. De Beers had work to do...

Demand-Side Manipulation

This is where the story gets crazy.

While the supply-side manipulation had worked wonders, diamonds were simply not a mainstay of the cultural zeitgeist. Some men gifted diamond engagement rings, but it was far from standard practice. Diamonds had remained a somewhat niche purchase of the ultra-rich. De Beers executives believed the price of the gem was depressed due to lack of demand.

So in 1938—at the start of the U.S. recovery from the Great Depression—De Beers commissioned N.W. Ayer, an advertising agency, to work on a diamond campaign.

Ayer set to work on two fronts:

  1. Convince men that diamonds were a show of love—and that the size and quality of the diamond was proportional to the size and quality of the love.

  2. Convince women that courtship and engagement involved a diamond.

A few of their inception-like tactics included:

  • Giving famous movie stars diamonds to wear in public. The original influencer marketing!

  • Seeding celebrity gossip publications with stories of the importance of diamonds to these movie stars.

  • Paying famous designers to talk about the “trend towards diamonds” on various broadcasts.

  • Commissioning a national lecture series at high schools on the topic of diamonds and their importance to engagements.

This was all focused on building a groundswell of demand. It was working, but the progress was slow. De Beers executives wanted something big and splashy—something to really move the needle. That something arrived in the late 1940s, when De Beers and Ayer crafted a slogan that would change the diamond world...forever.

"A Diamond Is Forever"

The slogan was—quite literally—perfect.

It elicits a feeling of eternal love, which is surely a romantic notion that any soon-to-be engaged person wants to create.

Perhaps even more importantly, it also limits the inclination to resell a diamond. If it is, in fact, forever, you should never resell it! Resales wreak havoc on pricing—and limit the impact of the De Beers supply controls—so by naturally limiting them, De Beers was creating another mechanism for keeping prices steady.

In a famous piece in The Atlantic, Ed Epstein commented on the slogan’s brilliance:

Even though diamonds can in fact be shattered, chipped, discolored, or incinerated to ash, the concept of eternity perfectly captured the magical qualities that the advertising agency wanted to attribute to diamonds.

Alongside the new flagship marketing campaign, De Beers quietly convinced men that the size and quality of the diamond was important.

The "two month salary rule”—that a man should spend two month's salary on a ring—was born (and then steadily inflated to three months over time).

So to any guys out there who are wondering where that crazy rule came from, now you know—it was just a clever marketing trick to get people to spend more.

The campaign was a smashing success.

Over the 40 years from 1939 to 1979, De Beers U.S. wholesale diamond sales skyrocketed from $23 million to $2.1 billion—a ~100x increase in annual sales.

De Beers had successfully manipulated demand on a grand scale and had the numbers to prove it.

They even replicated their tremendous U.S. success in Japan—a market that was notoriously hard to penetrate due to the high percentage of arranged marriages.

De Beers launched a campaign that positioned diamond engagement rings as tokens of modern Western values. In 1967, when the campaign began, just 5% of Japanese engagements involved a diamond engagement ring. By 1981, that figure was 60%.

They may not have been in 1938, but today, diamonds are a core part of the cultural zeitgeist. The De Beers marketing machine goes down as one of the most diabolically-successful in history.

Conclusion

The De Beers story is a fascinating modern case study on the potential impact of marketing on individuals and society. Humans are storytelling creatures—we are naturally drawn to great stories and great storytellers.

This is both a feature and a bug…

Today, De Beers is much less powerful than at its height in the mid-20th century, but its legacy and impact on the diamond industry remains extensive.

Broad-based cultural pushback against the dark side of the diamond industry—its roots in colonialization and the violence that continues to exist in its unregulated corners—has led to the rise of alternatives. Perhaps diamonds aren't forever after all?

To be sure, diamond engagement rings are still the standard in most Western cultures, but the ground may be shifting.

And rest assured, De Beers isn’t going down without a fight. Need proof? Check out source on this chart shared in Bloomberg Opinion a few weeks ago.
