The Double Mussel pendant is made of sterling silver and 18k gold and you can choose the finish between shiny and oxidized. You can choose the size of the cord, 40 cm or 45 cm. The mussel measures 1.5 cm x 1.8 cm (ring included) x 1 cm approximately. *Each mussel is handmade piece by piece. Therefore, the finishes may vary slightly from one jewel to another and it is for this reason that no two will ever be the same.
