Stories of St. Patrick tell of his creative use of the shamrock to teach the people about the Trinity. In this pendant, wonderful green Connemara marble has been hand carved and hand polished by skilled Irish craftsman. The high quality marble is inlaid in a sterling silver frame and comes with an 18" sterling silver chain. The shamrock measures approximately 1/2". Made in Ireland. Due to these items being handmade there may be slight variations.
