To choose the closest ring to your size, you can:

1. Measure an existing ring

- Simply outline the inner circumference of the ring on a piece of paper and measure the inner diameter or

- Place the existing ring through a ring size guide to determine the correct diameter and size number of the ring. 


2. Use string or paper

- If using a piece of paper, cut a thin, long strip (approximately 15 x 0.5cm). Wrap the string or piece of paper around the thickest part of the finger you wish to measure. Mark at the point the string or paper goes around the finger. 

- Lay the string or paper flat and measure its length up till the marking to get the circumference of your ring. If the circumference is in between sizes, opt for the larger size.
