Ring Size Guide

Hi M O O N Child,

We understand most people don´t know their ring size. So we hope the below information will help.

⇢ All our Moonstone rings come in US American sizes - we don´t offer half sizes ⇠

If you´re aware about your size you can check the table below to convert it into our US sizes.
Also if you already own a ring that properly fits the intended finger you could also use it to measure it in order to find out your ring size from the table below.

If you are between sizes, order up.






If you think now 
"Nice to know  - but I still have no idea what my ring size is..."
we´re here to help:

1. Get a non-stretchy string (or paper) about 6" long & 1/4" wide.
2. Wrap it around the spot of your finger where you intend to wear the ring. It has to fit snug, but not too tight.
3. Mark the point on the string (or paper) where it overlaps forming a circle.
4. Measure the length of the string (or paper) and check for the corresponding ring size in the chart.


A few tips from our side:

Make sure your finger is at a normal body temperature as fingers can shrink or expand when it´s cold or hot. If your knuckle is larger than your finger’s base, take two separate measurements & choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.


If you still don´t have a clue, check out the picture at the header for our ring size suggestions...
