Size Guide

Already own a ring of the same size you would like to purchase?

Just take a ruler and measure straight across the inside of the ring from inside edge to edge. Take the diameter measurement in inches or mm, and then use our measurement-conversion chart to find your ring size.

How to determine your size if you don't have a ring of the same size:

1. Take a piece of string, piece of paper and rap it around the base of the finger you would like to measure.
2. Use a pen to mark the point on the string or paper where it overlaps. The overlap will form a complete circle.
3. Take a ruler and measure the length of the string or paper from the starting end, to the end you marked with the pen.
4. Finally, use this measurement and compare it against the chart below to determine your ring size.
