Finding Your Perfect Fit
If you are between sizes, we generally recommend choosing the larger size for a more comfortable fit. The most accurate way to determine your ring size is to visit a jeweler for a professional sizing.
For the most accurate measurement, measure your finger at the end of the day when your fingers are typically at their largest.
