It’s said that the shamrock was plucked from the land by St Patrick to explain his belief in the Trinity. Today, many believe that wearing it will keep them safe. This sterling silver shamrock pendant is made of Connemara marble, known as “Ireland’s gemstone”, dating back millions of years. All our Connemara marble is authentic, coming from a family mine in Connemara. This sterling silver marble pendant has been Irish hallmarked in Dublin Castle.
