This beautiful Celtic Shamrock ring is made from sterling silver and 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, with each piece of jewellery unique. This stunning Shamrock ring features marcasite for extra sparkle and has been Irish hallmarked in Dublin Castle. Due to the unique patterns and colours of the marble, each ring may vary from the ones in our images.
