Are you unsure about your ring size? Have a look at this nifty guide below, which allows you to easily measure your ring size from home. How it works: Simply measure the diameter of a ring which fits comfortably on the finger that you would like to shop for - and see which letter it falls under.
Worried that your measurement may not be 100% accurate? Remember, the beauty of a stack ring is that they are easily interchangeable between fingers. If it doesn’t fit the finger you intended, simply swap it onto another - and you’re good to go!
