What Happens if I Need Ring Resizing?

If you’re your ring size to adjust existing fashion rings, women’s or men’s engagement rings or wedding bands you have in your collection, you may need to increase or decrease the size of your jewelry.

To make sure you get the best possible fit, the ring resizing process requires adding or removing small amounts of metal depending on the difference between the size purchased and the new size requested. As a result, your ring may be slightly thicker or thinner after resizing. These tiny changes are often visually imperceptible.

What If I Order The Wrong Ring Size? 

Don't let the question of size stress you out. 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, we offer a for your convenience.

Rings That Can't Be Resized

For example, diamond and gemstone eternity rings with a specific number of gemstones per finger size, migraine or ornate bands, silver rings, or rings with alternative metals such as Tungsten cannot be resized. 

We are happy to exchange your ring for another ring in the correct size within. It is important to note that should you opt for an exchange, your new ring may contain fewer or more gemstones, diamonds, or a reduction or increase in precious metal weight, which may cause an increase or decrease in the price.
