A breath of sea and sky
A breath of light and colour flows through this necklace, entirely handcrafted in Paris by master jewellers working for France’s most prestigious houses.
Suspended from a refined 18k yellow gold rectangle chain, five mobile pendants form a delicate, geometric line — inspired by the invisible structures of marine life.
Two tsavorites, two aquamarines, and a central blue sapphire create a subtle gradient of greens and blues, echoing the serene tones of the sea and the sky, while catching the light with quiet elegance.
A constellation of life
The design draws inspiration from Coscinodiscus Oculus Iridis, a microscopic diatom whose geometry evokes both the structure of the living world and a constellation of stars.
Each pendant flows like a ripple along the skin — luminous, alive, and delicately balanced between ocean depths and airy lightness.
