In order to determine your ring size, we suggest coming to see us for an exact measuring of your finger. We take all the following factors into determining the correct size. The size and shape of the ring, which finger they will wear the ring on, the size and shape of a person’s finger, the temperature of the hand and the size and shape of a person’s knuckle.
If you are trying to determine the size of someone’s finger you can use the two options below. This is only a guide and estimate. Costello Jewelry Company is not responsible for any sizing issues if size is based on the options in the pdf below.
