How to measure
With a ring that fits
Measure the inside diameter of a ring you wear on that finger, from edge to edge, in millimetres — and find it in the first column.
With a strip of paper
Wrap a thin strip of paper around the base of the finger, mark where it meets, and measure the length in millimetres — and find it in the second column.
Good to know
Measure in the evening, when fingers are a little larger, and not when your hands are cold. Between two sizes, choose the larger. A wide band sits tighter — take half a size up.
Not sure?
Come to the boutique in Yerevan and we will measure your finger — or write to us, and we will help you choose.
