The Trinity Knot, a traditional Celtic wedding band. The meaning of the Trinity Knot is ambiguous. It is believed that Christians view the three cornered knot as a representation of the Holy Trinity. Each corner of the knot standing for the Father, the Son and the Holy Spirit. Another, more basic belief is that the Trinity Knot stands for air, water and earth. Perhaps the Trinity Knot is expressing the cycle of life; birth, death and rebirth. Or even the Gods and Goddesses of Celtic lore. Whichever meaning you embrace, the Trinity Knot is a beautiful addition to your Celtic wedding band. Trinity Knot wedding rings, bearing this meaningful symbol, are available in gold, white gold and silver. There are solid and filigree styles suitable for both men and women.
