Sizing Guide
HOW TO USE THE RING SIZE CHART?

If you have a ring that perfectly fits the finger on which the Bizzotto Gioielli creation will be worn, you can place it over the nearest sized circle of the Ring Size Chart.

If your ring appears to be between two sizes, Bizzotto Gioielli recommends that the larger size be chosen.

The inner edge of the ring IS NOT ALIGNED with the outer edge of the circle.
