The new Durston Gem Ring Stretcher allows you to easily enlarge any stone-set ring. It works by stretching the metal, rolling out the shank and therefore enlarging the ring, without loosening the prongs or putting stress on the stone settings. The 17 piece roller set accommodates most ring sizes. The Gem Ring Stretcher is delivered in with an organiser to keep all parts together for easy storage.
The tool itself is made from powder coated cast iron to ensure a long service life. Pre-drilled holes offer you the opportunity to permanently attach to your bench for stability.
