Regular ring stretchers should not be used on stone-set rings. A ring roller rolls out the shanks, thus stretching the metal and enlarging the size without popping out the stones or damaging the settings. This ring roller comes with 17 polished rollers for different ring sizes and styles. It can also be used to enlarge wedding bands. We recommend using one of our steel mandrels and a rawhide mallet to complete the process.

Kassoy's ring sizers (finger sizers) measure in half-size increments, except for the RS676Q which has ¼ and ¾. sizes only. Our standard sizer is ideal for most rings. We recommend the wide band sizer for wedding bands and other large diameter rings. Our plastic finger sizer makes a great give-away—give it to a customer to bring it home to take measurements there.
