FAQ about choosing jewelry sizes
If you are hesitating between two sizes, we recommend choosing the larger one, especially if your fingers sometimes swell (e.g. in hot weather).
Usual lengthts are:
40 cm – close to the neck
45-50 cm – reaches the collarbone
55 cm – reaches the middle of the chest
Most of our necklaces have a 5 cm extension, so they can be adjusted.
Measure the circumference of your wrist and add 1-1.5 cm so that the bracelet is not too tight.
