In Celtic jewelry, the Celtic knot symbol is commonly known as the endless knot or even the mystic knot because it seemingly has no beginning or ending. The Celts thought that the knot could be a powerful symbol to ward off sickness or bad luck and thus wore it as jewelry, wove it into the patterns in their cloth, and placed it in their homes. To a modern mind, these knots symbolize the endless cycle of life and death present in the natural world, and it may have also had this significance to the ancient Celts. Many modern religious and spiritual symbols are common among the world's diverse cultures and religions.

For instance, the Trinity is a common motif in Celtic knots, as well as in the symbol known as the triqueta, or the triskelion. Although Ireland is mostly Catholic now, in the pre-Christian era, the tri-lobed or three-sided symbol does not stand just for the Catholic Trinity, but possibly incorporates these different trios of symbolic meanings: Spirit, Mind, Body; Mother, Father, Child; Past, Present, Future; or even, Mother, Maiden, Crone. It is also strongly believed that the Trinity stood for phases of the moon, often associated with the Great Mother, the lunar goddess who had three faces during the corresponding phases of the moon. In addition to the Great Mother, the Celtic Trinity symbol may also represent the three Bridgits. Bridgit is a goddess with three different aspects (faces) that stand for Art, Healing, and Metalsmithing. The triqueta is often seen with a circle around it, which stands for infinity. The circle shape of the ring also symbolizes protection and unity with the divine, so there are many meanings underlying the gift of Celtic wedding rings.

There are many variations of the Trinity symbol in Celtic wedding rings, from a Trinity knot filigree ring, to a design like a puzzle ring with interlocking bands that can be taken apart but never completely separated. The Triskelion symbol is another example of Celtic symbols with three parts. But, three is not the only number that figures prominently in Celtic designs. The Celtic Quarternary knot has many meanings, depending on which area and time period you are examining. The meanings for this knot even vary from artisan to artisan. The number five also crops up in Celtic knot designs, including the famous Celtic Five Fold, which has numerous symbolic meanings, as well as an association with the Celtic Fifth Element.
