A few things to keep in mind
If you’re between sizes, choose the larger size. Ring sizes are reasonably forgiving, but if your ring still feels slightly loose, every order includes a complimentary silicone ring size decreaser.
We'll also send you a free ring sizer, so you'll only need to measure with string on your first order.
We keep sizes 6, 7, 8, 9, 10, 11 and 12 ready to ship. For all other sizes, including half sizes, select “Custom Size” and allow an additional 5-10 days for production.
Buying for someone else? The most common men’s sizes are 9 and 10. The most common women’s sizes are 6 and 7.
If you select the wrong size, returns are straightforward. You can review our full Refund Policy.
