Ring Sizing Guide

The Diamantia Ring Size Guide

 

 

Whether you're buying a ring as a gift or want to know your own ring size, our helpful ring size guide will ensure you find the perfect fit.

 

 

Measure an existing ring

To find out the size of an existing ring, measure the inside diameter and use our ring size chart below (find the diameter in the "Inside Diameter" column and then check which letter it corresponds to) or follow these simple instructions using our printed guide:

 

  1. Select a ring that fits your desired finger
  2. Place the ring on the circles. The measurement shown refers to the inner diameter of the ring.
  3. If your ring falls between two sizes, order the larger size.

     

     

    Measure your finger

    Here's how to measure your finger using our paper ring sizer:

     

    1. Cut out the ring size.
    2. Place the end of the ring gauge through the slot indicated to make a loop.
    3. Wrap the loop around the desired finger with the letter size visible. The letter that appears closest to the slot is your ring size. Easy!

     

     

    Our advice:

    ~ 1 ~
    Measure your ring size at the end of the day when your fingers are at their largest.
    ~ 2 ~
    Do not measure your finger when your hands are cold because they can shrink to half the size of the ring.
    ~ 3 ~
    If you are between two sizes, always choose the larger one.
    ~ 4 ~
    You may need a larger size if you order a wider strap.
