A bracelet is perfectly sized when you measure your wrist tightly and add 1,5 cm. 

 If you are between sizes ask yourself how you like to wear your bracelet?

If you wear it tightly choose the smaller size and if you like to wear it loosely take the next size up.
If you wear your bracelet often then it will grow about 1 cm over the first year.

By over putting on and off the elastic bracelet, the aging process of the elasticity might manifest.


At AMA SPRING, all of our rings are made by hand in our local workshop. This means that we can make your ring specially to your exact ring size.

Buying new rings is easy if you already know your ring size.

If not, choosing the right ring size will take a bit of effort and time.
The size of the finger changes, even within the same day. It depends if it is morning or evening, if the weather is hot or cold…
We therefore recommend to measure  your ring size  in the middle of the day in a normal room temperature.
Also the width of the ring affects the size selection. Wide rings require approximately 5mm larger size.

If you want to have a ring in the same size as the one you already have, the easiest way to find out the size is to measure the inner diameter of the ring.
