More Ring Sizing Tips:

  1. The ring should fit your finger comfortably: snug enough so it won't fall off, but loose enough to slide over your knuckle with relative ease.
  2. When the knuckle is bigger than the base of the finger, measure both places and pick a size in between the two.
  3. Measure your ring size at the end of the day when your fingers are warm. Finger size changes depending on the time of day and the weather, and your fingers are actually smaller in the early morning and in cold weather. Also, keep in mind that fingers on your dominant hand are usually larger.
  4. Measure 2 to 3 times for more accuracy.

What Happens When My Ring Is Resized?

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.

The expert jewelry makers at ReadYourHeart adhere to strict quality standards so your resized ring both sparkles, and fits, beautifully. After the band is resized, each ring gets cleaned and polished before being returned to you.

Rings That Can't Be Resized

For example, diamond and gemstone eternity rings with a specific number of gemstones per finger size, milgrain 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 30 days of purchase. 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.
