These beautiful Trinity drop earrings are made of sterling silver and cubic zirconia. The tale of the Trinity Knot dates back centuries, when monks devoted themselves to illustrating the gospels. The result was the richly decorated knot-work which is instantly recognisable as Irish, and evokes Celtic culture. It is also symbolic of eternal life and the timeless nature of the human spirit. These sterling silver drop earrings have been Irish hallmarked in Dublin Castle.
