Gold plated (won’t tarnish) signet ring
You can measure your ring size using something like a string, floss, or a small strip of paper. Take one of these measurement tools and wrap it around the base of your finger, marking where the string or floss first overlaps, with a pen. Then, line that up with a ruler or measuring tape and take down its length in millimeters. Use the chart above to see which size is right for you.
