I bought this ring for my husband .
He loves it! He says - it’s very comfortable.
I’m thinking of getting him another one - for Father’s Day

I like

I wore a white gold ring originally and I jammed my finger so my finger swelled up and I bought a silver ring size 11 from Knot Theory. It was great until my sweeling went down and the ring easily came off. I never lost it though until I took it off on purpose to clean out my pool filter, I set it down some place and it disappeared. My nephew was here so I kind of think he took it. So I bought this pearl one in a size 10. Its definitely a more snug fit, and I do not worry about it coming off my finger anymore. It is great looking and very comfortable. I really like it.

Great alternative

Working in a museum where there is a risk to artifacts and antiques from my metal rings and diamond; and also a risk of personal injury from pinches and crushing from heavy antiques; the Knot Theory rings are a safer alternative while still allowing me to wear wedding bands. The stackable variety are nice, I can switch up the colour order.
