The Trinity Knot is a timeless emblem of unity, devotion, and infinite connection.

Encircling the entire band with 360-degree engraving, our Trinity Ring beautifully reflects the endless nature of love, faith, and life’s journey. Whether exchanged as a wedding band, anniversary gift, engagement ring, or personal keepsake, it is a powerful reminder of the bonds that shape us.

My husband is a now retired wild horse and burro specialist and wrangler. He he smashed his fingers at work and was unable to wear his wedding band afterwards (good thing he wasn’t wearing it or he’d have lost his ring finger). The silicone ring has been the perfect alternative and almost matches his burnished gold wedding band. We live in Wyoming, so the order took a bit to get here (a little over two months). However, the wait was well worth it! Thank you so much!
The ring is great! It looks wonderful and there are no weird breaks in the pattern like other silicone ring companies. The design is awesome and the color is exactly what I was looking for.
I did try to pick a size using their sizing chart and my previous silicone ring from a different brand. I feel like I might have been able to go a size down, though it might be more of a half size down.
I replaced my gold wedding band with this ring after getting my wedding ring caught on something and having to get the ring cut off. I was lucky that the result was only a wounded finger that healed. It could have easily been much worse. I had already been thinking about switching to a silicone ring because my wedding ring wasn't really able to slide off over my knuckle anymore and that made me feel a bit nervous about it. So after some research, Knot Theory seemed like the best company to order a ring from.
I'm very happy with quality of my ring and I love the look of it. People have commented on it and have been surprised to find out that it's a silicone ring because of the quality of the design. I have recommended Knot Theory rings to other people and will continue to order from them when I want or need a new ring again.
Make sure to get a good measurement of your ring size, and you're sure to get a perfect fit. I was way off with my first attempt and initially ordered a ring 2-3 sizes too large. Thankfully, their perfect fit guarantee allows for one-time free replacement if your ring doesn't fit properly, so I re-measured and got one that's a much closer fit.
Everything came in as ordered but mine was too big. I’m thinking I have to reorder w the proper size of my finger. Apparently I’ve lost weight. I’m guessing this is the case. My fault.
I love my silicone Trinity Knot ring so much - I ordered one for my wife too!!
Due to my Rheumatoid Arthritis, my hands swell all the time - my original metal ring became too uncomfortable to wear all the time - so I decided to research a silicone ring and found Knot Theory - they have the same design as our original Trinity Knot rings we got from Ireland - no brainer there - I am so happy with my new ring - Thank you for creating such innovative designs and making your rings genuinely worth getting - HIGHLY RECOMMENDED!!
I am really pleased with the ring.
Sooo comfortable.
I am very happy I purchased this ring, the comfort, design and durability are wonderful. I will purchase another one as a back up.

Rings are very nicely made and dealing with KNOT has been great. II had an issue with the ring being too large because of a Jewlery store gave me the wrong size. KNOT graciously helped me order a second ring. They were fantastic to deal with and any issues I had was on me. Thanks KNOT
I have been very happy with my purchase. My old silicone ring failed after a year, so I have high opes that this will last a good while.
Very impressed with the fit and comfort of the ring, as well as the degree of precision of the engraving. Disappointed I was unable to get the multicolored one, hopefully in the future.
We absolutely love our knot theory rings. Bought the standard silicon cosmic purple when we got married because we both work around machines. Then I lost some weight so upgraded to the trinity knot design and fell in love with them.
I got this for my husband because he works with his hands, and his gold wedding band was getting scratched up. He loves the design and feel of the silicone ring. I think he will wear this a lot!

It is a great ring. The engraving was exactly the way I ordered it. It was one size too big for my son (13). But he just decided to switch fingers and said that he'll grow into it. Very true.
First ring was a little big. Got second one free and fits great! Thank you
This ring is beautiful and my husband loves it.
