Sizing Rings on a Ring MandrelA55S
If you need to size a ring up within a 0.25 (1/4) to 0.50 (1/2) ring size, and there are no settings with stones in your ring band, then the ring mandrel and a hammer are the tools you need.
If you are sizing a ring with a bezel or setting, without a stone, follow Steps 1 - 3 but avoid hitting the area with the setting, so as not to damage it.
To size a ring up within the 0.25-0.50 size range, with a setting with a stone in place, be sure to use the ring stretcher that is suited for this task, as well as review the instructions and 3D animated how-to video ''Ring Stretcher'' and illustrated instructions to see how the process works.
If you need to size a ring higher than 0.25-0.50 a ring size, it is best to seek help from a jeweler who can insert a section of metal into your ring seamlessly.
If you want to use the Ring Mandrel to form a ring band from a strip of wire, review the instructions for ''Rings Around the Finger.''
