Choosing the correct ring size is essential for a comfortable fit, especially since some rings with stone settings cannot be resized.

Ring size system is based on the inner circumference of the ring in millimeters. Here’s a quick guide to help you find the perfect size.

If available, use a ring sizer tool to measure the inner circumference in millimeters directly. Measure your finger at the end of the day, as fingers tend to be slightly larger then. Avoid measuring in cold temperatures, as fingers may temporarily shrink.
