This 14K yellow gold Otiumberg moon earring has been developed in close collaboration with a piercing expert using antibacterial, nickel-free and hypoallergenic materials. For pierced ears, this single piece features an internally threaded post and interchangeable front end. Seeking eco-friendly jewellery can feel like asking for the moon and stars, but this Otiumberg earring is carbon-neutral and responsibly handmade with recycled raw materials.
