Trinity Knot Engagement Rings

A trinity knot engagement ring sets a center stone between Celtic trinity knots, the three-pointed knot also called the triquetra. Our trinity knot engagement rings are made in 10K and 14K gold with round lab-grown diamonds from 1/2 carat to 1 carat, a 1 carat heart-shaped lab-grown diamond, and natural or lab-grown emeralds, plus a diamond trinity knot bridal set with a matching band.

The trinity knot is drawn as one unbroken line looping through three points, so it has no beginning and no end. On an engagement ring, couples read the three points as past, present and future, or as love, honor and protection, and many Irish Catholic families see the Holy Trinity. Read more in our trinity knot meaning guide.

Choosing the stone comes down to look and meaning. A lab-grown diamond gives the brightness of a classic solitaire at a gentler price than a mined diamond of the same size. An emerald brings the green of Ireland; it is softer than diamond, so it rewards a little care. White gold makes a diamond look icier, and yellow gold warms an emerald's green.

Each product page lists the metal, stone and carat weight. Measure with our free ring sizer, then pair your ring with a band from our Celtic wedding rings. For more styles see all Celtic engagement rings, or wear the knot every day with our trinity knot necklaces.

Trinity Knot Engagement Rings Questions

What does a trinity knot engagement ring symbolize?

A trinity knot engagement ring symbolizes eternal love, because the knot is one continuous line with no beginning and no end. Its three points are often read as past, present and future, or love, honor and protection, and Christians see the Holy Trinity. It is a popular choice for couples with Irish roots.

What carat sizes do your trinity knot engagement rings come in?

Our 14K gold trinity knot engagement rings come with a 1/2 carat or 1 carat round lab-grown diamond, and there is also a 1 carat heart-shaped lab-grown diamond style. Emerald styles are set in 10K or 14K gold. Each product page gives the exact stone size and metal.

Should I choose a diamond or an emerald trinity knot ring?

Choose a diamond for maximum sparkle and durability, since diamond is the hardest gemstone. Choose an emerald for color and Irish meaning, as green is the color of the Emerald Isle. Emerald is softer and can chip with hard knocks, so it suits someone who will take the ring off for heavy work.

Is there a matching wedding band for a trinity knot engagement ring?

Yes. Our Diamond Trinity Knot Engagement Wedding Ring Set pairs an engagement ring with a matching band, and our Celtic wedding rings include trinity knot bands in several metals. Choose the same metal color as the engagement ring so the two rings sit well together on the finger.

Is a trinity knot the same as a triquetra?

Yes. Triquetra is the Latin name for the three-pointed knot, and trinity knot is the name most used in Ireland. Some versions add a circle woven through the three points, which many read as the unbroken circle of eternal love. Both appear on Irish engagement and wedding rings.
