Just as Balenciaga released their Tool Bracelet – essentially a hose clamp – competitor Cartier has also released a line of hardware-based jewelry, called Écrou de Cartier. So “écrou” means “nut” in French, but read the product copy: “The Écrou de Cartier challenges the status quo of design through its unique play on the industrial. Movable bolts are perched on a circular ridged band, creating unique pieces that defy conventions. Just like that, the ordinary is made beautiful.”
In addition to bracelets, they’ve got rings, earrings and necklaces as well. The rings start at $2,430; the earrings, $2,790 (each, not for a pair); the bracelets start at $7,150, while the necklace will set you back $16,500.
