This beautiful marble is over 900 million years old and it only found in the remote and rugged region of Connemara on Ireland’s Atlantic coast. Each piece of our jewellery created using this treasured natural stone is totally unique as no two pieces of the famed marble are the same. This piece has been Irish hallmarked by the Assay office in Dublin Castle. All our Connemara Marble is certified Authentic and supplied by Joyce marble quarries in the Beanna Beola mountain range of Connemara, Ireland.
