Durston 1303 Gem Ring Stretcher

The new Durston Gem Ring Stretcher allows you to easily enlarge any stone-set ring. It works by selectively stretching the ring shank opposite the setting. Choose the correct roller that matches the ring shank and then place the ring shank on the center die. Roll back and forth across the bottom of the ring shank to gently stretch the metal. While not suitable for all stone set rings, you can stretch most rings and then gently round the entire ring on a steel ring mandrel to finish. The 17 piece roller set accommodates most ring shank thicknesses.
