Latest / Pricing Power Podcast with Fexingo: How Businesses Set Prices, Raise Margins, and Win Customers / How Tiffany Priced Diamonds Without Owning a Mine
Transcript
- Lucas: Tiffany & Co. does not own a single diamond mine. Not one. And yet, its average price per carat in 2023 was roughly 40 percent higher than Cartier's — a competitor that sources from exactly the same mines in Botswana, Russia, and Canada. Luna: That's a huge gap. So the premium isn't just about the blue box? It has to be something in the supply chain itself. Lucas: Exactly. The conventional story is that Tiffany's pricing power is pure brand magic — the robin's-egg blue, the Audrey Hepburn association, the Fifth Avenue flagship. And that's part of it, sure. But the durable pricing advantage comes from a century-long project of vertical integration that most luxury brands never attempted. Luna: Walk me through that. Because vertical integration usually means owning the mine, the factory, the retail stores. Tiffany doesn't own a mine. Lucas: Right — they skip the mine and own everything downstream. It starts with Charles Lewis Tiffany himself in the 1880s. In 1887, the French Crown Jewels were auctioned off after the fall of the monarchy. Most buyers saw a chaotic sale with uncertain valuations. Charles Lewis saw an arbitrage. Lucas: He bought a chunk of the collection at distressed prices — some reports say he paid roughly 20 percent of what the stones were worth — then resold them at a public auction in New York for about a 300 percent markup. That single move established Tiffany as the house that could price diamonds with authority, not just sell them. Luna: So the pricing power started with a trade, not a brand campaign. That's a different origin story. Lucas: It is. And that trade gave Tiffany the capital and credibility to do something no other jeweler had done: build a diamond-cutting workshop in-house. In the 1960s, Tiffany opened its own cutting facility in New York. Before that, almost all diamonds were cut by independent artisans in Antwerp or Tel Aviv. Tiffany wanted control over cut quality — which directly determines how a stone sparkles, and therefore what you can charge for it. Luna: That's a smart bottleneck. If you control the cut, you control the light performance — and the price. Lucas: Exactly. And they went further. In the 1970s, Tiffany built its own gemological laboratory — a grading lab that certifies every diamond they sell. Most jewelers rely on independent labs like GIA or AGS. Tiffany uses its own standards, which are stricter than industry norms. They reject stones that would pass GIA's color and clarity grades. Luna: So if a diamond gets a Tiffany certificate, it's effectively a higher grade than the same stone with a GIA certificate? That's a built-in quality premium. Lucas: That's exactly the mechanism. It means a Tiffany diamond with a 'G' color grade actually performs like a 'F' or 'E' under industry grading. The customer pays for the Tiffany name, but they're also getting a physically better stone. The brand premium is backed by real product differentiation. Luna: And the secret supply agreement with De Beers? I've heard rumors about that. Lucas: It's not a rumor. For decades, De Beers controlled about 80 to 90 percent of the rough diamond market. They had a sightholder system — a select list of buyers who got first pick of the rough. Tiffany was one of the few retail brands ever granted sightholder status. Most sightholders were cutting houses or wholesalers. Tiffany got direct access to the best rough, before anyone else could bid on it. Luna: So they cherry-picked the top parcels. That's a structural advantage you can't replicate with marketing spend. Lucas: You can't. And the agreement came with a condition: Tiffany agreed never to advertise or promote De Beers directly. It was a quiet backroom deal that gave Tiffany exclusive access to the highest-quality rough for decades. That access translated into a consistent supply of stones that competitors simply couldn't get. Lucas: Now, the De Beers monopoly has broken apart — today they control maybe 30 percent of rough supply. But by the time that happened, Tiffany had already built alternative sourcing relationships. They now buy from mines in Canada and Russia, often on long-term contracts that lock in volume and quality. The pricing power didn't vanish; it just evolved. Luna: I want to test this. If the pricing power is really about supply chain control, why couldn't LVMH — after buying Tiffany in 2021 for about 16 billion dollars — replicate that for its other brands? Why can't they make Bulgari or Cartier charge the same premium? Lucas: Great question. LVMH tried. After the acquisition, they brought Tiffany's supply chain expertise in-house. But the problem is that Tiffany's advantage is path-dependent — it took 130 years to build those relationships, that grading lab, those cutting covenants. You can't buy a diamond-cutting workshop tomorrow and have its output trusted by customers the same way. Trust is a time compounder. Luna: So Tiffany's pricing power is a moat built in decades, not dollars. That's why LVMH paid a premium for the company: they bought the supply chain history, not just the brand. Lucas: Exactly. And the numbers bear that out. According to a 2023 Bain luxury report, Tiffany's average retail price per carat was about 24,000 dollars. Cartier was around 17,000. The gap is roughly 7,000 dollars per carat. Part of that is the blue box, sure. But a big chunk is the consistent cut quality and grading that Cartier can't match because they don't own those operations. Luna: There's a lesson here for any business selling a premium product. You can't just put a fancy logo on a commodity and expect a premium to stick. You need a real bottleneck somewhere in the chain. Lucas: That's the takeaway. Pricing power that lasts comes from controlling a step in the value chain that your competitors can't easily replicate. It could be a proprietary manufacturing process, a long-term supply contract, a certification standard you set — something real, not just a marketing story. Tiffany's story shows that if the bottleneck is credible, the premium is durable. Lucas: And honestly, if this episode moved your thinking forward in some small way — gave you a concrete case to apply to your own business — that's exactly the kind of conversation we hope pays for itself. The show stays ad-free because of listener support at places like buy me a coffee dot com slash fexingo. It's the smallest possible ask, and it genuinely makes a difference. Luna: Yeah, and it's not about big pledges. It's more like — if today was worth a coffee to you, that's the link. Really simple. Lucas: So back to the diamond. If you're a founder or a product manager listening, the question is: where in your supply chain is your equivalent of Tiffany's grading lab? What's the one thing you control that your competitors can't easily copy? Because that's where your real pricing power lives. Luna: And if you don't have one yet, you know where to start building. Thanks, Lucas. Lucas: Thanks, Luna. See you next time.
