The Hydra Necklace from the OVERTONE collection is crafted in sterling silver and inspired by the fluid movement of ocean kelp. Individually sculpted links precisely soldered together create a chain designed for graceful movement and elegant drape across the décolletage. Pair with the Hydra Pendant for a considered, sculptural statement.

Sterling silver naturally evolves over time. Regular wear can help slow tarnishing, as your skin’s natural oils help maintain its shine.
Store your jewellery in a soft pouch or jewellery box to prevent scratches and keep it in a cool, dry environment away from direct sunlight and heat.
Avoid chlorine and harsh chemicals. To restore shine, gently polish with a soft silver cloth or use a specially formulated Silver Dip. You are also welcome to visit a SARAH & SEBASTIAN store for professional polishing.
