These striking sterling silver stud 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, and each piece of jewellery is unique. These round earrings are surrounded by beautiful Celtic knot-work, and have been Irish hallmarked in Dublin Castle.
