Ring Sizing Guide
Advice for measuring your ring size.
1: Your finger size can change throughout the day, so we recommend measuring at the end of the day when your fingers are at their largest. Do not measure when your hands are too hot or cold as it may not be an accurate result.
2: Rings with a wide band will feel tighter than with a thin band. In these cases, we recommend buying a full size larger than your normal ring size or visiting our showroom for an accurate measurement.
3: If it's a surprise, try borrowing his or her ring (from the correct finger) and use the ring sizing guide to determine its size or visit our showroom and let us measure it for you.
4: Your ring should fit your finger comfortably. It should be snug enough so that it will not fall off, but loose enough to slide over your knuckle and feel comfortable when wearing.
Contact Us for more information on measuring your ring size. We have years of experience and will talk you through all your options including, secretly getting your partners finger size and re-sizing rings to ensure the most perfect fit possible.
