These elegant sterling silver shamrock earrings are made from Connemara marble, a unique stone that dates back over 900 million years and is known as “Ireland’s gemstone”. All of our Connemara marble is truly authentic, coming from the Joyce family mine in Connemara, County Galway. These earrings feature the iconic shamrock, and marcasite for extra sparkle. They have been Irish hallmarked in Dublin Castle.
