Cartier
By the Encore Luxe specialists · Updated October 2026
Edward VII is said to have called Cartier "the jeweller of kings and the king of jewellers". The house earned the description over generations: it designed tiaras for royal houses, the first modern men's wristwatch for an aviator, and some of the most recognisable jewellery of the twentieth century. Through it all runs a clarity of line that makes a Cartier piece recognisable at a glance. This guide introduces the house, its icons and what our specialists look at in a pre-loved Cartier piece.

A short history
Louis-François Cartier took over his master's Paris workshop in 1847. Under his grandsons, Louis, Pierre and Jacques, Cartier became an international house, with branches in Paris, London and New York. Louis Cartier designed the Santos in 1904 for the aviator Alberto Santos-Dumont, who wanted to read the time without taking his hands off the controls, and the Tank in 1917, inspired by the shape of tanks on the Western Front.
Jeanne Toussaint, director of fine jewellery from 1933, made the panther a Cartier emblem. In 1969 Aldo Cipullo designed the Love bracelet, followed in the 1970s by the nail bracelet later relaunched as Juste un Clou. In the 1970s the Les Must de Cartier line brought the house to a wider audience with leather goods, lighters and more accessible jewellery.

Choosing pre-loved Cartier
For bracelets, size comes first. The Love bracelet and Juste un Clou are rigid forms that sit close to the wrist, so a centimetre makes a real difference to how they wear. Our listings give the size of every piece, and our client team can help you choose.
Next, consider gold. Cartier's yellow gold is warm and classic, white gold is cool and pairs naturally with diamonds, and rose gold has a soft, flattering warmth. Many people mix them, as the Trinity ring does.
Then think about model. Many Cartier designs come in a classic and a small model, and with or without diamonds. The small models are finer and stack easily; the classics have more presence.
Condition matters less on gold than on leather, but we still describe it carefully. Fine surface scratches are normal on polished gold that has been worn. Dents, worn engraving and loose stones are not, and our listings always describe them. We also note any polishing or resizing we can see.
For watches, our listings give case size and describe the case, dial, crystal, strap or bracelet and movement, along with any service history.
The language of Cartier
Juste un Clou means "just a nail". Panthère is the panther motif. Must de Cartier is the house's line of leather goods and accessories. Au 750 marks 18-carat gold. Pavé describes diamonds set closely together. Our glossary explains these and more.
