Cartier’s Juste un Clou bracelet was first released in 1971, but don’t let that fool you into thinking enthusiasm for the label’s iconic jewellery collection has waned over the last 40 years: quite the contrary. Inspired by the industrial aesthetic of bolts and screws, the Cartier nail ring, bracelet and necklace have since been updated with intricately set pavé diamonds and a variety of precious metals – these are pieces that will hold their value among collectors for years to come.
