This ring is made of hallmarked sterling silver and is designed with a shamrock with a marcasite finish. The Shamrock is the unofficial and most recognizable, symbol of Ireland. It was the Celtic druids who first used the shamrock as an important part of their culture. The Celts believed that everything important in the world came in threes; Three stages of life, three elements, three domains; earth,sea and sky, past, present and future. They believed the number three to be a perfect number and, as such, to have inherent mystical powers St. Patrick, when he set out to covert the Celtic inhabitants of Ireland, recognized the importance of the shamrock to the Celts and, according to legend, he used the plant to illustrate the Christian concept of the Trinity.
