Ocean diamonds
A breath of brilliance flows through this delicate necklace, handcrafted in Paris by master jewellers working for France’s most prestigious houses.
Suspended from a refined rectangle chain in 18k yellow gold, a single geometric pendant is crowned with a brilliant diamond — like a spark drawn from the ocean, clear and vibrant.
Thoughtfully designed to be worn alone or layered, the Stellar Necklace brings together traditional craftsmanship, quiet sensuality, and the poetry of the living world.
A luminous, singular piece — to keep the sea close, wherever you are.
A constellation of life
This creation draws inspiration from Coscinodiscus Oculus Iridis, a microscopic marine diatom whose structure echoes both the architecture of life and a constellation of stars.
Minimal and radiant, the pendant sits like a point of light on the skin — fluid, precise, and full of presence.

How to wear & customise
