Jewellery Sizing

Please try to provide us with the correct ring size when you place your order. Any of our rings can be resized when purchased through our website except for eternity bands. We recommend confirming the required size with a local jeweller wherever possible, as this is the most accurate. Alternatively, please have a look at our ‘ring sizing guide’ for a DIY way to measure ring size. If you live in the UK, you can also request a plastic ring gauge that we can send to you - please note these methods are more of an indication, and not as accurate as a professional sizing. If you do provide us with the wrong size then we will happily resize the ring for you once free of charge within three months of purchase, plus shipping. If it needs a second resize or falls outside of this time line, this will be a chargeable service and will be quoted for based on the complexity of the resize, plus shipping. Shipping, handling and custom fees for resizes are the sole responsibility of the customer.  

You can also refer to the table below to establish your ring size based on the inside circumference of each ring size. Please note that this is a guide only and that having your finger precisely measured by a professional with the correct tools is the most accurate way to find out your ring size. Please note that ring size conversions are accurate to within approximately 1/4 of a finger size.

Tips for Measuring your Ring Size

— Your finger size can change during the day – the best time to measure is at the end of the day when your fingers are at their largest. Do not measure when your hands are cold as your fingers could be up to half a size smaller than usual!
— A wider band will feel tighter than a narrower band. When purchasing a particularly wide band, we recommend choosing a full size larger than your normal ring size.
— Your ring should fit your finger comfortably: it should be snug enough not to fall off, but loose enough to slide over your knuckle.
