Sizing

Most rings can be easily resized 2 sizes up or down, many can be sized further. If there's a ring in particular you want information on, just start a chat or use the 'Ask Us' option on any product page. For our UK customers we offer our Free Resizing service, see the page for details.

The easiest way to make sure a ring is going to fit someone is to ask their ring size, perhaps they already know or have a ring that fits already that can be used as a guide.

If you're looking to keep your ring a surprise you can take a ring you know fits to any High Street jeweller and they'll easily tell you the size for free. Another method is to cut a piece of paper into a strip, fold it around either the finger of choice or inside a ring you know will fit and mark where it wraps. You can then compare that circumference with the size chart here:​
