Ring Sizing
Option 1: follow these steps to find appropriate size.
Ring Test:
Measure the inside diameter of a ring that fits. Make sure it is in the centre or largest area of the circle (pictured below). This is the internal diameter.
String or Paper Test: You will need a thread or a piece of paper, a pen and a ruler.
1. Take a small thread or a piece of paper and wrap it snugly around the base of your finger. (For the most accurate result, pull paper as tight as possible.)
2. With a pen mark the spot at which the thread overlaps its end on your finger.
3. Measure the length of the thread in millimeters.
Option 2: Visit a local jeweller who will be able to size you on the spot.
