Edgy design aside, what you’ll appreciate most about this piece is how surprisingly lightweight it is. (That’s because the elongated eighteen-karat-gold links, while chunkier than average, are hollow in the center.) Also noteworthy: the pavé-adorned carabiner in place of a traditional clasp.

• 18kt yellow gold, 0.38ct pavé diamond
