Consider both style and versatility. The most universally flattering lengths are between 16–18" inches, which sit gracefully at the collarbone and suit most. Longer chains, typically 20–24" inches, create a bolder statement and allow for effortless layering with other necklaces. Think about the recipient’s neckline preferences and personal style to find the ideal fit. If you’re still unsure, we recommend using our online Necklaces & Pendants Size Guide, or visiting a Tiffany store for expert assistance.
