If your girlfriend wears a ring on finger ring, it is easiest to measure that one. Borrow it and measure the inner diameter of the ring. In this case it is important to realize if the hand is dominant, the ring finger may be stronger than on the left hand.
If it is a ring that she wears less - borrow it and take it straight to us. In our showroom we will measure it and you will be guaranteed the right size.
Another option is to trace the inner side of the ring to the paper.
You can also try the ring on one of your fingers and then try to measure rings in our showroom.
You can also ask her girlfriends, who are already married or engaged, to let try their ring at their meetings. Your girlfriend's friends will surely be happy to tell you what size her ideally fit. A beautiful role in this case can be played by a mommy, who lets your girlfriend try some of her rings.
Do you like to go on design markets or similar event? You will always find at such festivals a booth of promising jewelry designers, who mostly have the ring-shaped thorns. Maybe she will want to try a ring or buy one? You can use the situation beautifully to measure!
