- If you are aiming for a surprise, ask your partner's parent or one of her close friends if they know her finger size.
- Borrow one of your partner's rings and use the Ring Sizing Guide above to determine its size. The ring should be from the correct finger on the correct hand.
- The average finger size is a 6 to 6.5 for women, and 9 to 10 for men. When no other information is available to you, selecting one of these sizes is your best choice.
- If the ring you select does not fit when you receive it, we are happy to resize it for you within 30 days. Please contact us for return instructions.
