Tiffany & Co.

Tiffany sells jewellery through its own stores, and the only unusual thing about the model is how much of the price is ritual rather than material. An engagement ring is not a purchase a customer optimises; it is a purchase she must be able to describe afterwards. Tiffany spent a hundred and forty years making sure the describable answer was its own name, and the blue box is the mechanism — the packaging is recognised before the object inside it.

Underneath the ritual is a genuinely operational company. Tiffany runs diamond processing operations across Belgium, Botswana, Cambodia, Mauritius and Vietnam, cutting and polishing a meaningful share of the stones it sells. That vertical position gives it something rivals struggle to match: provenance. Since 2019 Tiffany has published the region of origin for its newly sourced individually registered diamonds, which converts an ethical commitment into a marketing asset and a supply-chain moat at the same time.

Since LVMH took ownership in January 2021 the model has been pushed upmarket, hard. Price points have been raised, high jewellery has been expanded, silver entry products have been de-emphasised, and the Fifth Avenue flagship was rebuilt at a reported cost above $350 million — described by LVMH executives as the largest retail investment in the group's history. Bernard Arnault told analysts in January 2025 that Tiffany's revenue had doubled and its jewellery sales quadrupled since the acquisition. That is an executive claim, not a disclosure: LVMH does not report Tiffany separately.

Tiffany's moat is the deepest in this library and also the most specific: it owns the default answer to a question every couple asks once.

The foundation is a nineteenth-century accumulation of authority. Charles Lewis Tiffany bought French crown jewels during the 1848 revolution and was called the King of Diamonds for it. In 1878 he acquired a 287.42-carat rough yellow stone from the Kimberley mine and had it cut, unusually, for brilliance rather than size — 128.54 carats, 82 facets. In 1867 Tiffany became the first American firm to win a grand prize for jewellery at the Paris Exposition. An American company established European-grade authority in a European category, which had never been done.

The mechanism is the 1886 Tiffany Setting: six prongs lifting the stone clear of the band so light enters from beneath. It is a better design, but that is not why it matters. It made the diamond the point of the ring, and it made a specific shape the visual shorthand for engagement worldwide. Tiffany did not just sell into a ritual; it wrote one.

The seal is the colour. Tiffany Blue is a trademarked, non-registrable-by-anyone-else shade, standardised as a custom Pantone numbered 1837 for the founding year. The box is recognised at a distance before the jewellery is seen. Almost no consumer brand on earth owns a colour this cleanly.

The crack: lab-grown diamonds. A physically and chemically identical stone now costs a fraction of a mined one and the gap keeps widening. Tiffany does not sell them in fine jewellery, which is the right positioning decision and also an admission that the category's price architecture is under attack from below.

Tiffany's history is a hundred-and-eighty-year experiment in what owners do to brands, run three times with three different answers.

The first owner was the founder's family, and it built the moat: the Setting, the colour, the Blue Book, the crown jewels. The second was Avon, which bought Tiffany in 1978 for around $104 million and treated a jeweller like a cosmetics business — mass-market lines, discount distribution, and by the early 1980s a brand that had been genuinely cheapened. Avon sold it in 1984 to an investor group led by William Chaney for roughly $135 million, and Chaney spent the next fifteen years undoing the damage before and after the 1987 IPO. That six-year interlude is the most compact case study in luxury of what happens when a company that understands volume buys a company that runs on scarcity.

The third owner is LVMH, and so far it has done the opposite of Avon: raise prices, narrow the entry range, spend $350 million on one store, install Anthony Ledru from Louis Vuitton and Alexandre Arnault on product and communication. Capital has gone into the brand rather than out of it.

The unresolved question is the price. $15.8 billion at roughly 29 times trailing earnings requires a very long compounding runway to justify. LVMH has probably earned that return operationally; nobody outside the group can verify it, and that is a governance fact worth naming rather than excusing.
