There are several different ring-sizing systems worldwide. Kviksølv works with the metric system.
The best way for measuring your ring size is going to a jeweller for a professional true fitting. It is also possible to measure a ring that fits you comfortably on the intended finger. (Please note that the right and left hand can be different)
If these options are not possible for you please email us and we will send a ring-sizing gauge (and detailed instructions) to you.
If the ring is a gift and it is impossible to provide with a size, we can send a ring that is in stock and make one to size later. This does mean that extra shipping costs are applicable.
