Trinity Knot Necklace

A Trinity knot necklace features the triquetra — three interlaced arcs woven into one unbroken loop, an ancient Celtic symbol of eternity, unity, and the enduring bond of three-in-one. With no beginning and no end, the Trinity knot has long stood for love, friendship, and faith that lasts forever, which is why it's one of the most meaningful pieces in Irish jewelry. The Irish Jewelry Company has designed original Trinity knot necklaces since 2006, in sterling silver, 10K and 14K gold, and two-tone finishes.

The Meaning Behind the Triquetra

The triquetra is drawn from a single continuous line, so it has no start and no finish — the reason it came to represent eternity and an unbreakable connection. Its three points have carried many meanings over the centuries: mind, body, and spirit; past, present, and future; and the three-in-one of faith. Because the knot loops back into itself endlessly, a Trinity knot necklace makes a heartfelt gift for a partner, a close friend, or a family member — a wearable symbol of a bond that holds.
