Precious Carbon Ring Size Guide

Ring Size Guide

Your experience with diamond jewelry should be as flawless as your cuts. That’s why at Precious Carbon, we’ve crafted a ring sizing page that makes getting the perfect fit simple, accurate, and stress-free.

Why Ring Sizing Matters

A well-fitted ring offers comfort, security, and elegance. Whether it's an engagement ring or a timeless band, the right size prevents slipping, avoids resizing hassles, and ensures lifelong wearability. A slightly ill-fitting ring can feel uncomfortable or risk damage to delicate settings.

How to Measure Your Ring Size at Home

Printable Ring Size Chart (Preferred Method)

  • Print the chart at 100% scale (make sure it isn't resized by checking with a ruler). Simply follow the guide, and you'll know your size in just a few minutes.
  • Place a ring that fits you well directly on the chart and match the inner edge to find your size.
  • Or use the paper sizer: cut, wrap it snugly around your finger, and note the size where it overlaps.

String or Paper Strip Method

String or Paper Strip Method
  • Wrap a thin strip of paper, floss, or string around your finger's base.
  • Mark the overlap, measure the length in millimeters, and match it to the size chart.
  • This method is quick but less precise than the printable chart.

Measure an Existing Ring

Measure an Existing Ring
  • Use calipers or a ruler to measure the inner diameter of a ring that fits well.
