Cartier Juste un Clou*: The In-Match Bracelet of Choice of Top WTA Tour Players

After just the first five days of the U.S. Open I've already spotted it on Paula Badosa and Yulia Putintseva; in the past it was a staple of Genie Bouchard, among others.

$3,600-$85,500.

From websites:

"Juste un Clou" is a French phrase that translates to "just a nail." It refers to a Cartier jewelry collection that includes a nail-shaped bracelet, rings, brooches, necklaces, and earrings. The collection was designed by Aldo Cipullo and debuted in 1971. The bracelet was originally called the "Nail bracelet," but was renamed "Juste un Clou" in the 2000s.

The collection is known for its bold, sleek, and minimalist design; avant-garde style; embracing the idea of finding beauty in everyday objects; challenging conventional norms of jewelry making.

The collection is available in yellow gold, rose gold, and white gold, and in paved and non-paved designs. The bracelet is durable enough to wear every day, including in the shower.
