Terra | 1/3″ (8 Mm) Polished Black Tungsten Carbide Ring

The string test

• Wrap a piece of dental floss or string around the part of your finger you want to measure.
• Make sure it’s very tight. Most people order rings too large.

• Where the string overlaps, mark that spot with a pen.

• Measure the distance between the two marks in millimetres. This is the circumference of your finger and equivalent to your ring size (EU size).

• If you’re between two sizes, we recommend that you round down to the next size.
• Buy your favorite ring.
