De Cosmi fine jewelry is designed by multidisciplinary artist Catherine Servel, and hand made in our ateliers in New York, NY and Arles, France.
All of our pieces are crafted in ecologically sourced and recycled 18k yellow gold and solid sterling silver, and Catherine searches the world for the most beautiful and unique stones, pearls, and shells to inspire and inform her design process.

Since launching De Cosmi in 2019, the brand has been featured in W, Le Monde, The New York Times, Elle, Harper's Bazaar, Dazed, and Document. We've also been featured in exhibits at Foam Fotografiemusem, the Frauenmuseum, and La Maison Close.

De Cosmi has been worn by accomplished actors and musicians including Julia Garner, Millie Bobby Brown, Isabella Rossellini, Sharon Horgan, Hailee Steinfeld, and Shailene Woodley, among others.

Today, De Cosmi's full collection can be seen in our showroom at 12 rue de la Liberté just off the historic Place du Forum in Arles.
