The Triquetra can be simple or complex and is the most profound of Celtic Knots. Trinity Knots are an ancient Celtic symbol that speaks of the power of Three in all things: earth, sea, and sky; birth, death, and rebirth; as well as past, present, and future. This handcrafted, sterling silver Triquetra pendant features intricate, concentric knotwork and is an elegant testament to the triplicities surrounding us.
