This ring stretcher is specially built to enlarge any stone-set ring without loosening prongs or stressing settings. The 16-piece roller set (included) accommodates most ring styles. How to use: Match shank width of the ring to one of the rollers. Fix matching roller to stretcher by removing pin on U section at the end of the handle. This is done by pulling upwards. Remove the roller that’s already there & replace with chosen roller and replace the pin. Insert shank of ring between the two rollers & move handle from side to side to stretch the metal. Please note only the back of the shank should be worked on ( only to be used on gem set rings) Rings should not be stretched more than 2 sizes & only if the shank is thick enough.
