Your sizing questions

How do I find my ring size without a ring sizer?
Wrap a thread or a narrow paper strip around the base of the finger, mark where it meets, then measure the length in millimetres with a ruler. That measurement is the circumference: read it in our chart to get the North American size.
How do I measure using a ring she already wears?
Place the ring on a ruler and measure the inside diameter, inner edge to inner edge, in millimetres. A 17.3 mm diameter equals a size 7. Use a ring worn on the ring finger, never the thumb or index.
How can I buy a surprise ring without knowing the size?
Go with size 6½: it is the most common women's size in Quebec. You then have 30 days to exchange the piece for another creation or a boutique credit. Write to us before ordering and we will guide you discreetly.
What time of day should I measure?
At the end of the day, at normal temperature. Fingers swell with heat, salt and exercise, and shrink in the cold. If your measurement falls between two sizes, take the larger one.
Does a wide band need a different size?
Yes. A band of 6 mm or more sits tighter: usually take half a size up from a slim band.
