A few things to keep in mind
If you'd prefer, we can send you a free ring sizer here. We include one of these with every ring order, so you'll only need to measure with string on your first order.
If you’re between sizes, choose the larger size. If your ring feels slightly loose, every order includes a complimentary silicone ring size decreaser.
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.
