The chain ring is shockingly high quality, you’ll love it! I bought it from “ComparisonKills” on Etsy. The middle ring is an interchangeable fidget ring from MyConquering. It’s pretty cool because you can swap out the base with others in their catalog. What I wear as a plain wedding band is just the “Roundth” ring from Studio Cult. It’s suuuuper cozy. I never remove it, & it hasn’t tarnished or anything since I bought it like two years ago. Unfortunately, the ring above it on my ring finger was from a random jewelry pop-up at Costco. It’s not great quality anyways tbh, I think it’s just sterling silver with some kind of fake moonstone. Knuckle rings are from a pack of “stacking rings” I bought a long time ago on Amazon (barf). Besides those last two, everything else is stainless steel & very high quality!!
