Connemara marble is an attractive form of marble found in Western Ireland. Typically green in colour, it is said to be one of the rarest forms of marble due to limited supply. Twisting bands of serpentine produce an array of bewitching green shades in Connemara marble which makes it so attractive for jewellery. The marble itself is formed when limestone is subjected to high pressure and high temperature. Known as ‘The Irish Gemstone’ Connemara marble is thought to be over 600 million years old.
