Parts of Four - Parts of Four's one-of-a-kind blue Talisman necklace is thread with an uncut aquamarine pendant, a spiritual healing stone thought to bring calmness to the wearer. It's handcrafted from oxidised sterling silver for a purposefully well-worn effect that develops over wear and engraved with a logo at the T-bar fastening. Wear it as a good-luck piece alongside everyday outfits.
