Most jewelry designers, like parents, refuse to play favorites. Not Sharon Khazzam: “This is probably one of my favorite pieces ever.” Though the 285.26 ct. Mosaic Cuff took about a year to make, the idea came six or seven years ago. “I drew it in my sketchbook, and every year I came back to it and thought, I’m going to do it,” says Khazzam. When she decided to start, she sent the concept to one of her collector clients. From there, “every stone I picked, every color I chose was with her in mind. It was made for her wrist.” The woman received not only the cuff but also a book detailing its creation. “The art of jewelry design is so, so important,” she says. “The drawing, all the work behind the scenes”—for Khazzam, that’s as precious as any gem.
