De Beers Case Study

Carrying on the MBA content series, I’d like to highlight a case study we ran through last term on DeBeers. It’s a pretty standard study that I expect a lot of business schools use. I hope you’ll find it illustrative.

Almost every business school student knows that the value of diamonds is vastly inflated, and in large part that’s due to the work of the DeBeers company. In a nutshell, here’s how they did it:

  • Through a series of nifty deals, they chiefed all of the diamond mines they could lay their hands on. Initially, these were all located in the same area, making this possible. This gave DeBeers a virtual monopoly on diamond production.
  • DeBeers mined at a regular rate, but stockpiled most of it, only letting a trickle out into the market. This artificial scarcity is what drove prices up.
  • If another mine came online that didn’t play ball, DeBeers would flood the market with specifically the type of diamond that mine produced, driving down their revenue stream.
  • Then, an awesome marketing campaign. The phrase “Diamonds are Forever” is a product of the DeBeers company. As a result, engagement and wedding rings almost always have one or more diamonds in.
  • They then moved to control the distribution chain, by being pretty crappy to jewellers. Since DB had monopoly of the product and created demand, the distribution chain were left with little leverage.

So, everything was hunky-dory, until a few things happened:

  • Those pesky miners kept discovering mines in different places. DeBeers normally just bought the things, but they couldn’t keep on doing that.
  • As soon as their production monopoly started to disappear, distributors got an incentive to go elsewhere.
  • Since the marketing campaign was about diamonds rather than DeBeers, suddenly their traditional marketing campaign was working for their competitors.
  • Everybody went to see Blood Diamond.

The answer?

  • DeBeers was and is awesome at marketing, so they shifted to market DeBeers diamonds instead of diamonds generally.
  • They certified that their diamonds as conflict free.
  • And the biggie – they opened retail stores, and started making jewellery.

And I found myself walking past the DeBeers shop in London the other day. Here’s what it looks like:


Was going into retail the right direction? There’s no easy answer – they are now able market directly to the consumer a product that can be tied directly to a store and a retail experience, but they are in direct conflict with their own distribution channel.

Time will tell!

  1. Interesting thoughts. Perhaps one other alternative they could have considered was to explore other precious metals/stones mines, bought ’em out, and campaign those in a similar air as they formerly did with the diamond mines. Then again, I wonder if the brand would get diluted or if DB would carry over into things like platinum, sapphires, etc.

    Yay b-skool…can’t wait to go to class again tomorrow! 🙂

  2. did Blood Diamond really play a role in the whole thing? Thats just the one point i am not so sure of…
    only 3% of diamonds in the entire industry was involved for the war, wasn’t it?

    nice post 🙂

  4. Hi Sameer – thanks for getting in touch. I’m not part of Adcom, so I can’t give you an official advice, but I’m happy to share my take on your situation. I’ll pop an email over to you.


  5. do you think DeBeers currently follows an inside-out perspective(resource based) or an outside-in perspective(market based)??
