Ring Size Guide
When ordering a ring, it is always important to choose the correct finger size. To obtain an accurate measurement we always recommend having your finger professional measured in a jewellers or arranging a jewellery consultation with our personal jewellers.
However we know this is not always possible so we have put together some guides to help you when it comes to measuring the size for your piece of jewellery.
Below is a ring size conversion chart and a printable ring sizing tool to help you gain the most accurate finger size. Alternatively we can also post you a ring sizer to try at home if you email us.
Bear in mind that when ordering wider bands such as wedding rings, the width of the ring needs to be taken into consideration. If you contact us with your normal size we can advise the size to order taking the desired width into account.
