Determine the correct size of your ring

1st method: using a ring you already own (diameter)

You already have a ring on hand? Then simply measure the inside diameter of the ring. You can then find your size by converting using the table above.

If you can't find your exact size, then take the next size up.

2nd method: measure the circumference of your finger

To find out your ring size, simply take a piece of wire, dental floss or paper. Wrap it loosely around the spot on your finger where you want to wear the ring and mark where it overlaps. Then measure the length. The millimeters measured reflect the inner circumference of the ring.

If you can't find your exact size in the chart above, then take the size that is above. For example, if your finger circumference is 57mm, then take the size 58.


Example : 52 mm (circumference)




The mood ring is a jewel that can be personalised infinitely. It is a stylised expression of Swiss design.

Dark green open addon. Made of anodised aluminium.

The speech : 

We are proud to be able to present "open mood". This novelty will form your jewel not with both parts of the base, but with only one, freeing the piece from one part of its structure. Stylish and balanced with its clean profiles, clever with its invisible mechanism and, above all, always customizable, according to the mood... For sure, open mood belongs to the mood family. In fact, it is made from a segment of the metal base of the original mood ring. It is a new step in the evolution of the brand, but it has freed itself from part of the metal base and thus offers more lightness and a larger surface area for colour and customisation. 

Made of anodised aluminium, mood has combined high-tech production with a handmade finish that makes the alumimium ultra-light and highly resistant, with a powerful colour.

Design by Cedric Chevalley

And ... practically?

As you will have understood, the open mood ring is a revolution in the world of mood and marks the beginning of a new era... The OPEN addon is worn on a "normal" base by being inserted on the part with the small slots. The open addon can be worn on a wide, small, black, etc. base.
