How to find your finger size?
The easiest way to get your finger size is to go to a reputable jeweler and have it measured accurately.
Another popular way is to simply measure the inside diameter of a ring you already own, worn on the same finger as the one you wish to order.
Please note that the measurement must be very precise and calculated in tenths of a millimeter.
