Let customers speak for us
from 83058 reviewsWe love the rings ours are custom engraved inside. They fit as expected and feel very durable. We are already thinking of getting another pair.
I’m really enjoying my rings from Knot Theory and would buy more if the accent rings with the rope pattern came in more colors. I’d love to see a gold.
I work as a mechanic, welder, fabricator, and plant maintenance technician (2 jobs, one is my dream, one is my livelihood). I can't afford to lose a finger or break/damage my "dress ring". Knot Theory rings are and ecellent and customizable, stylish alternative where you can still be and individual, save money, and be safe. I would recommend these to anyone looking for a silicone ring option for whatever the reason they are looking. We got my wife onw as well and we were able to add text to both rings that we share as a private joke.
I ordered 2 lily of the valley rings for my husband and me. They look neat and feel very comfortable. They might have slightly stretched over the first 2 weeks of wearing them, so it might be worth ordering a size under...
I have nothing but positive energy for this company. I bought a ring for my wife and it was too small and when I needed to return it they made the process seamless! So thanks again for your assistance. By the way, she loves her ring!
I’ve been debating on getting this ring for a while, but I’m so glad I did. It’s my favorite shade of green, but the quality is •amazing•! I was definitely purchase again.
Both rings were as described. Comfortable to wear
Love the color. Fits just right. The only think I wish I could change is I like a wider band.
I bought this to wear on my forefinger when I'm camping as I usually I have a gold and diamond band on, and that isn't camping jewelry. And I had to have something there as I fidget with the ring. This is perfect and I pair it with a thin gold filled band. Elegant and clean looking.
Wearing the ring and great look and work with it on and love it.
I have been looking for a silicone ring for a horse lover (me) and nothing out there. I found this one, my favorite color is blue, and the horses are generic enough it could be most any breed! Thank you!
Hubby is a diesel mechanic and he loves it. Said its comfy to wear while working and he doesn't have to worry about metal ring hazards.
Greek Key Silicone Wedding Ring - Engraved Dual Layer
Love my horse ring. It will remind me of my horse that passed on.
Great experience all around with Knot Theroy. The quality of the ring is nice. The detail is beautiful. The customer service was prompt when I got the incorrect size and I got a replacement no questions asked. What more could you want?!
