Porter Open Diamond Ring

Method 1

Materials needed: ribbon or a strip of paper and a ruler.

1. Cut a strip of paper or ribbon and wrap it around your finger. Use a pen to mark where the two ends meet.
2. Using a ruler, measure the length ribbon or paper in millimeters. If you are between sizes, size up. If the ring you'd like is thicker/rider - like the Rose Ring, size up as well. 

Method 2

Using an existing ring that already fits you well, you can use a ruler to measure the inside diameter of this ring. Just use a ruler and measure straight across the inside of the ring from edge to edge. 

Also Keep In Mind:

• Fingers typically measure larger in the summer when it is hotter and smaller in the winter when it is cold.

• Fingers measure larger in the morning than in the afternoon.

• Fingers on your dominant hand are often larger than on your non-dominant hand.

• As a general rule of thumb, the wider the band, the snugger the fit so consider sizing up on all rings with larger bands.
