”Love symbols should suggest an everlasting quality,” Italian jewelry designer Aldo Cipullo once said. His solution in 1969 was the Love bracelet, which requires a tiny screwdriver to put on and take off. The now-iconic Cartier Love bracelet also holds 102% of its retail value on the resale market, making it a must-have Cartier piece.

In the 1970s, the New York-based Cipullo followed the success of the Cartier Love bracelet with another piece of jewelry inspired by everyday hardware — the Just un Clou (Just a Nail) bracelet. The simple bracelet emulates a curved nail that wraps around the wrist. The Juste un Clou bracelet is also a great investment, carrying 101% of its primary market value at resale.

Diamonds make everything better, especially in terms of investment! Love 4 Diamond — the Cartier Love bracelet adorned with diamonds — is a good investment, holding 95% of its primary market retail value on the secondary market.

Prefer rings over bracelets? Cipullo’s Cartier Juste un Clou ring takes the same idea as the Juste un Clou bracelet, turning it into a minimal ring with a hard edge. This piece from the Cartier Juste un Clou collection holds its weight on the secondary market, with an average retention value of 94% at resale. 

If you’re looking for something other than a piece from the Love or Juste un Clou collections, the Trinity pendant necklace is another worthwhile investment from Cartier. Initially designed in 1924 as a ring in three intertwining metals (gold, white gold, and rose gold) by Louis Cartier, the French jewelry house’s namesake, the pendant version holds 87% of its primary market value at resale.
