One of my favourite pieces from Estee LaLonde's collection for Daisy Jewellery, this Luna Lock necklace is timeless, and will go with everything. It also comes in gold. £149.

The one-and-only silver punk lock necklace belongs to Stewart and her alone. The good news: Today, Dempsey is launching a new necklace inspired by the original: The Lip Locket Necklace.
