All of our jewels are guaranteed being in sterling silver (925/000) and 18-carats gold (750/000).
They do not contain nickel and do not provoke any allergies.
We only use real natural stones from Corsica and the real Mediterranean Eye of Saint Lucia (see our explainations to differenciate opercula from warm seas).
The small opercula are picked up on the beaches of Corsica, and the biggest ones are collected in the sea by professional fishermen.
The red coral from our jewels is the real Corallium Rubrum of the Mediterranean.
