The “Iridis” necklace is made of solid sterling silver plated with 24 carat gold, mounted on an adjustable 50-55cm cable chain in solid sterling silver also plated with 24 carat gold.
The sterling silver and 24-carat gold are certified recycled by our supplier based in Lyon (France).
About the Collection “The Diatoms” (in French “Les Diatomées”’)
Like the rest of the collection, the “Iridis” necklace represents the plankton, the natural jewel of the microscopic world in the Ocean. More specifically among the plankton, diatoms are single- celled brown microalgae that make up most of the phytoplankton and produce a quarter of the Earth oxygen. The particularity of diatoms is to have a membrane surrounded by a transparent siliceous shell, sensitive to pollution.
Because Diatoms are magnificent and precious for life, they need to be protected: that is why our brand Sœur & Mer dedicated its first collection to them in order to raise awareness as they are unknown to most people.
Thanks to you, through your acquisition of one of our pieces of jewelry, our brand is able to make a 5% donation to the Tara Ocean Foundation, developing an innovative and
original open ocean science which, in the future, will enable us to predict, anticipate, better understand climate risks and better protect biodiversity.
About the “Iridis” necklace:
Close to a work of art, the design nearly presents four thousand five hundred details to reveal the mathematical beauty that can be found in real life with the “Coscinodiscus Oculus Iridis” Diatom, that measures a fraction of millimeter and yet is so beautiful and complex it is close to perfection.
Also available in solid sterling silver.
