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)

"Magma" is a diminutive of "Metamorphic Rock" which means "resulting from the transformation in the solid state of old sedimentary or magmatic rocks subjected to temperatures and pressures different from those which existed at the time of their formation".

About mood

Welcome to the world of the interchangeable and customizable mood ring. mood is more than a ring, it is a timeless and androgynous jewel. It is an infinitely customizable accessory.

Create your ring according to your desires.

A steel structure forms the base of the jewel on which a ring is housed. The centerpiece consists of two separable elements that support and hold the central ring called add-on. The special architecture gives the owner of the ring a great deal of freedom, who can very easily change the look of his jewelry by changing the add/on.

To further expand the mood potentialities, rings in various colors and materials are available.

The addon is the interchangeable part that fits in the center of the ring. All our addons are compatible with the majority of bases (large, small, etc.).
