The Ecrou de Cartier
Just like the Juste un Clou (and in fact, inspired by it), the Ecrou de Cartier draws from industrial elements. In this case, it’s nuts and bolts rather than a nail, hence the name Ecrou, French for nut. The ridged band features movable bolt details and comes in yellow gold, rose gold, and white gold (some sparkling with diamonds), adding industrial glamour to your stack.
