Brilliant Earth is happy to assist you in determining the correct ring size. Keep in mind that the most accurate way to size a finger is to have it sized by a local jeweler using professional techniques.

We suggest that you print this guide and read the instructions to ensure accurate sizing. Before you print, be sure to check that page scaling is set to "none" on your print dialog box.

• 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.
• If you are having difficulty using our printable ring sizing guide, please contact us to request a complimentary plastic ring sizer be mailed to you. Your plastic ring sizer will arrive within five to seven business days.
