HOW TO GAUGE YOUR RING SIZE
Prior to purchasing your custom engraved signet ring online, please be sure of your ring size.
A properly-sized ring will fit comfortably on your finger, but will be a little hard to get off. Since the ring has to travel over your knuckle, the ring size is really the size of your knuckle, not the part of your finger below it.
For accurate sizing of your signet ring we recommend you get measured by at least two independent jeweller, trying on similar signet rings for comport fit, If you have a ring that fits you comfortably, take it to a jeweller and have it measured for size. Sizing should be measured from the centre of the ring.
Ring sizers and measuring techniques can vary from one jewellery shop to another. Get sized at a few different shops. If sizing's vary, take the average.
Under ideal circumstances it would be advisable to take measurements at different times of the day to allow for expansion and contraction of the finger due to changes in temperature, exercise, menstrual cycle or fluid retention.
