Iona Marble is found by diving from the beaches into under-water seams on the Isle of Iona, Scotland. This 2700 million year old rock is composed of a unique combination of serpentine and limestone. Known by some as the sacred stone of Columba, green marble has been treasured and crafted by jewellers for centuries. On the Isle of Iona the fishermen would not leave port without their lucky green gems. It has been used by healers to help the body return to a time unhindered by the stresses and pollution of modern times.
