The Trinity Knot is a wonderful symbol of Irish history and tradition, a reminder of many centuries ago when the Book of Kells was first created. Today, the richly decorated knot-work tells a tale of enduring love and eternal life, with neither beginning nor end. These beautiful 9K gold earrings would make an ideal gift. These gold Trinity Knot earrings also come with a guarantee of authenticity, having been Irish hallmarked by the Assay office in Dublin Castle.
