How do I find my ring size? Firstly, visit your local jewellery store and measure your finger. Stores that offer a sizing service will do the best job. It’s best to try on a ring of a similar width and profile as the one you wish to order. A correctly sized ring should sit comfortably on the finger, without loosening or falling off if you’re shaking your hand. It should come off relatively easily when pulled, but not slide off instantly. See our Sizing and Care page for more detailed information, or, if it’s a surprise for someone else then please see the ‘I don’t know the ring size and it’s a surprise!‘ FAQ.
