A line of light, born from the ocean
A fine, radiant bracelet set with a brilliant-cut black diamond, suspended on a rectangular high-end rhodium-plated silver chain.
Its graphic yet fluid design draws inspiration from the invisible architecture of marine life — a jewel that feels alive against the skin.
Minimalist yet full of meaning, this singular bracelet is a quiet echo of the sea — a reminder you can wear every day, wherever you are.
A constellation of life
Inspired by Coscinodiscus Oculus Iridis, a microscopic ocean diatom, this bracelet reflects the secret geometry of the living world, like a constellation traced beneath the surface of the water.
Craftsmanship & Ethics
Handcrafted to order in our Parisian atelier by master jewellers using traditional fine jewellery techniques.
Each bracelet can be personalised on request: chain length, number of motifs, choice of fine stones.
Sœur & Mer supports the Fondation Tara Océan, dedicated to ocean preservation and the protection of invisible marine life.
How to wear & customise
Adjustable from 14 to 16 cm, this bracelet can be worn alone or layered with other Stellar creations — in subtle gradients of aquamarines, sapphires, tsavorites or spessartite garnets.
A jewel to compose like a bouquet of rare stones — designed to be worn, gifted, or passed on. It carries the values of Sœur & Mer: link, love, family, transmission, and optimism.
