Sizing

To determine your ring size, measure your finger's circumference and refer to the chart below. For accuracy, have a jeweler measure your finger. It's crucial to measure multiple times on different days and times. If you're between sizes, choose the smaller one. Match the circumference in millimeters with the corresponding ring size on the chart.
