Size guide

How to find your ring size — and the sizes of necklaces, bracelets and pendants.

Rings

Ring sizes are European: a size is the inside circumference of the ring, in millimetres — a size 52 measures 52 mm around. Every size from 44 to 71 can be ordered.

With a ring you already wear

Take a ring that fits the finger you have in mind — round, not dented. Measure its inside diameter with a ruler, from edge to edge, and find it in the table. Or print our ring sizer and lay the ring on its circles.

Print the ring sizer

With a strip of paper

Wrap a strip of paper, about 1 cm wide, around the base of your finger — over the knuckle if it is wider: the ring has to pass over it. Mark where the paper overlaps, unroll it and measure the length in millimetres. That length is your size.

Measure at the end of the day, with warm hands: fingers are slimmer in the morning and in the cold.
Your two hands are not the same: measure the one you will wear the ring on.
If you hesitate between two sizes, choose the larger one.
A wide band, like the Band-Aid rings, fits more snugly than a thin one.
The surest way: have your finger measured at the studio in Brussels, by appointment.

All ring sizes from 44 to 71 can be ordered online, at the same price. Each ring has its usual sizes; any other size is handcrafted for you — made to order, it cannot be returned. For a size beyond 71, or to have a ring resized, write to us.

Necklaces

All necklaces can be worn at different lengths: one necklace closes in two or three lengths. The length depends on the design — see the dimensions of each piece.

Bracelets

Bracelets come in standard sizes, depending on the design, and most close in two different lengths.

Pendants

Pendants come in different sizes, listed in their description, and can be worn on the LIAISON necklace — you can compose your own by choosing several pendants.

Adjustment

Customer satisfaction is very important to us. Adjustment, repair or cleaning of your Isabelle Lenfant jewelry is part of our after-sale care. Please write to us first at isabellelenfant@gmail.com; once you have our confirmation, the pieces can be sent to the studio at your own expense.

If the piece you ordered does not fit, we exchange it once for the right size and send it back to you, with additional shipping costs. Further size adjustments are at your own cost.

Before sending a piece to the studio, write to us at isabellelenfant@gmail.com. Delivery & Returns
