For Rings. How to choose a correct ring size?

Please use the methods described in the guide below with caution! Even a slight error can result in a ring that is uncomfortable to wear or does not fit at all. You use these DIY measurement methods at your own risk, and we accept no responsibility for any discrepancies in size.
The most accurate method is to have your size measured at a jewelry workshop or store. Professionals use specialized tools—such as ring sizers and sizing gauges—to determine the correct size with high precision.
