Radiance in motion
A refined composition in motion — this Cocktail Necklace features a single golden pendant, suspended from a delicate rectangle chain in 18k yellow gold and set with 16 colourful stones: diamonds, blue, yellow and pink sapphires, aquamarines, tsavorites and spessartites.
Handcrafted in Paris by master jewellers, it reveals a vibrant geometry inspired by the invisible structures of ocean life.
The pendant rests lightly on the skin, like a shell cradling its secret: a constellation of gemstones, nestled at the centre of a hollow form shaped by light and living memory.
A constellation of life
This design draws its inspiration from Coscinodiscus Oculus Iridis, a microscopic marine diatom whose symmetry evokes both natural architecture and starlit constellations.
A luminous, singular jewel — feminine, fluid, and rich in presence — to carry the sea close to the heart, wherever you are.
Gemstones & Gold
- Diamonds, blue, yellow & pink sapphires, aquamarines, tsavorites, spessartite garnets

Craftsmanship & Ethics
Made to order in our Parisian atelier using traditional fine jewellery techniques.
