This Elegant Pendant is the perfect addition to your Irish Jewelry Collection. These shamrock earrings with 3 clear cubic zirconia stones. The shamrock is undoubtedly one of the most iconic emblems of Ireland. Traditionally it is said that while Christianising Ireland in the Fifth Century St. Patrick used the leaf to explain Christian doctrine of the Holy Trinity that God is made up of three parts; the Father, Son and Holy Spirit. One God in three persons. As Ireland's patron saint the shamrock has been used as Ireland's emblem for hundreds of years.
