CF Concept Ring Sizes

Our rings come in the standard UK sizes as follows: K, M, P (small, medium, large).

If you are unsure of your size:

- visit your local jewellers where you can usually have your ring size measured. 

- measure the inside diameter of a ring you already own and refer to the ring size chart below.

- measure the circumference of the intended finger and refer to the ring size chart below.

- if your size falls between two sizes - opt for the larger size. 

If you need a different size, that is not provided in the drop down menu, please let us know at checkout and will will re-size the ring before it is sent out. There is no extra cost for this.
