The Balenciaga line of jewelry includes this patented single knot cuff that comes in many variations. The US patent awarded for this design, to Isabelle Guichot, former Balenciaga CEO, is USD730765 titled Bracelet.
As a reminder, the difference between a US design patent and a US utility patent is the following:
“a “utility patent” protects the way an article is used and works (35 U.S.C. 101), while a "design patent" protects the way an article looks (35 U.S.C. 171)” (USPTO)
A figure drawing of the design on file for the patent, and an image of the marketed Balenciaga product, called the single knot cuff, in silver and gold, are included below.
