Easily enlarge any stone-set ring with this ring enlarger. It works by rolling out the shank, stretching the metal and enlarging the ring without loosening prongs or stressing stone settings. The 17-piece roller set (included) accommodates most ring styles that are size 4-3/4 or larger. Includes an organizer case to keep everything together and easily accessible.
Made from cast-iron and powder-coated for a long service life, this tool can be permanently attached to your bench using the pre-drilled base holes.
