Irish Flag Shamrock Charm

The Shamrock has become famous across the world as a symbol for Irish heritage, which is evident on March 17th, when the world and it's Irish descendants celebrate St. Patrick's Day.
St. Patrick used the shamrock, a three-leaved clover, to explain the Christian concept of the Holy Trinity i.e. the theory that God the Father, God the Son and God the Holy Spirit are each separate elements of just one entity.
