This Four strand Neckpiece is made from Sea Bamboo an alternative to coral which is rare and endangered. It has a sterling silver clasp and a triangular detail of slightly larger beads which are 10mm in diameter. I imagine a bright neckpiece like this could be worn during winter to remind yourself that Spring is on its way.
Persephone spent six months of the year in the underworld during which winter gripped the land. Each spring when she would again return to the world to visit her mother Demeter the first shoots would appear.
