The "Diatom" drop earrings, White Gold, Blue Sapphire

Because diatoms are sublime and precious for life, yet little known and in need of research, Sœur et Mer dedicates its first collections to them and supports at the Tara Ocean Foundation involved in researching the impact of climate change and pollution on marine microorganisms, educating young people, and mobilizing political decision-makers.

A jewel that's a perfect match for the extremely fine and precious Diatoms or Grams collection.

Treat yourself and your loved ones!
