The best and most reliable way to determine your ring size is to be measured at a jewellers shop.

Please ensure you are measured using a sizer of a similar band width to the ring style you wish to purchase as this can change the size noticeably.

Alternatively, you can cheaply and easily purchase a ring sizing belt from an online market place. 

All Nicola Lawrence Jewellery rings are sized using the British Wheatsheaf scale.
