Blue Nile Ring Resizing Policy

At Blue Nile, we provide complimentary resizing for most engagement rings and wedding bands within the manufacturer's recommended sizing range during the first year. If you need a different ring to accommodate a more significant size change, we offer a 30-day exchange policy for your convenience. After the first sizing or outside of one year, sizing fees may apply.


Some of our ring styles cannot be resized due to their design. In these cases, a note or an icon will appear on the product detail page under the ring size selection.  Diamond and gemstone eternity rings with gems all around the band circumference, milgrain or ornate wedding bands, silver rings, or rings with alternative metals such as tungsten are examples of rings that cannot be resized. 

We offer several free tools to help you measure ring size at home including a plastic ring sizer and printable ring size chart. Our customer service team is happy to help with further assistance in finding the perfect fit.

Please note that the ring resizing process can result in small amounts of metal being added or removed from your ring to adjust the size as requested. As a result, your ring may be slightly thicker or thinner when the sizing is completed. Typically, any differences are minor. Rest assured that our expert jewelers thoroughly inspect every ring to ensure it has been resized properly and adheres to our strict quality standards.
