At B2C Jewels we understand what a perfect fit means while shopping online.
Simply follow any of our two methods to find your exact ring size
A) Do it Yourself Method:
- 1. Wrap a thin strip of paper or string around the base of the finger that will wear the ring.
- 2. Mark on the paper or string where it overlaps on itself.
- 3. Use the ruler to measure the length of paper or string from its leading edge to the mark.
- 4. Use that measurement to find the corresponding ring size in the adjoining chart.
