Sizing Tips

  • If you are in between sizes, go bigger (you can always exchange if it's not your perfect fit).

  • Make sure to measure the finger that you want to buy for, different fingers will likely need different sized rings.

  • Contact us for assistance if you're still not sure

What if my ring doesn't fit when it arrives?

We have a 30 day exchange policy, so you can easily return the ring and re-order another size.
