Both of these take something from a hardware shop, a nail, a bolt, a length of chain, and make it fine jewellery, which is exactly why a certain kind of lady buys them for herself. The Cartier Juste un Clou is a wrapped gold nail; the Tiffany HardWear is a ball-and-link chain worn like a piece of jewellery should never quite be. Pre-owned, a classic gold Juste un Clou bracelet sits around £5,500 to £7,000 and a gold HardWear link bracelet around £4,700 to £10,700 as of July 2026, so the difference is really about how tough you want to look.
A nail, or a chain
The Juste un Clou is Cartier being witty: Aldo Cipullo took an ordinary nail in the 1970s and bent it round the wrist, and it has read as quietly rebellious ever since. The Tiffany HardWear, reimagined by Francesca Amfitheatrof, is blunter and more downtown, all graduated metal balls and heavy links, jewellery with a bit of a swagger. Both are for a lady who does not want anything fussy or floral, but the Cartier is sleeker and the Tiffany is bolder.
How much does each cost pre-owned?
The lines split very differently by metal, so a like-for-like table is the only fair way to read them. Here is where they sit on the UK pre-owned market as of July 2026.
| What you are buying | Tiffany HardWear (pre-owned, Jul 2026) | Cartier Juste un Clou (pre-owned, Jul 2026) |
|---|---|---|
| Most affordable way in | sterling-silver ball pieces, ~£230–£750 | single plain-gold hoop earring, ~£500–£800 |
| Gold ring | link ring, pave white gold, ~£7,500 | ring, plain gold, ~£900–£2,300 |
| Gold bracelet | link / wrap bracelet, gold, ~£4,700–£10,700 | bracelet, classic plain gold, ~£5,500–£7,000 |
| Gold necklace | graduated link necklace, gold, ~£3,800–£11,600 | necklace, small model, gold, ~£3,000–£4,500 |
| With diamonds | pave link ring, ~£7,500 | bracelet, white gold + diamonds, ~£9,700–£16,500 |
The big difference is at the entry: the HardWear has a whole sterling-silver side, so you can own a real Tiffany HardWear piece for a couple of hundred pounds, while the Juste un Clou is gold only and starts around £500 for a single earring or £900 for a small ring. In gold, the two bracelets are close, within a few hundred pounds; the Juste un Clou ring is much gentler than a HardWear gold ring; and both climb past £9,000 once you add diamonds. If budget is the deciding factor, the HardWear in silver is the softest landing; in gold, they are genuine rivals.
Which suits how you actually live?
Choose the Juste un Clou if you want the sleeker, more grown-up version of the idea, a single clean line of gold that dresses up or down. Choose the HardWear if you want more attitude and more metal, and if starting in silver and adding gold later suits how you buy. Both are unfussy, both wear every day, and both look best worn with a bit of nonchalance rather than kept for occasions.
Buying either one pre-owned
Both have held up well second-hand, which is a description of how they have behaved rather than investment advice, and values can fall as well as rise. Whichever way you lean, buy a piece that has been authenticated, checked and guaranteed, so it is simply yours to wear.
