Ordering the correct size
Your ring should fit comfortably, snug enough that it doesn’t fall off, but loose enough to slide over your knuckle. Finger size can change depending on the time of day and the weather. For best results, check your size at the end of the day when your fingers are warm. If you are buying for someone else, try to borrow a ring (from the correct finger).
