Jewels & Gems only uses the U.S. sizing system, to find your ring size, just convert yours (U.K., French, Italian, etc) to the corresponding U.S ring size.
Please note: for rings with a thin band (such as our Signe Ring) don't be afraid to go half a size smaller of what you usually wear, while for rings with a thicker band (such as our Kai or Freya Rings) we recommend to go half size up.
If you do not know or still remain unsure of your ring size we highly recommend getting sized by your local jeweler, it's a quick and easy process.
If you do know your size, here is guide that you can refer to for conversion.
