Georg Jensen Mercy 18ct Yellow Gold Single Ear Cuff Earring, 20001080. The Mercy collection was designed by Jacqueline Rabun, the acclaimed American designer known for her emotional approach and a design language characterised by sculptural and organic forms. Crafted from 18ct yellow gold, the Mercy single ear cuff requires no piercing and it slides onto the ear, sitting like a conch piercing. This ear cuff will arrive beautifully packaged in a unique Georg Jensen presentation box.
