The Durston Gem Ring Stretcher offers a quick and easy solution for increasing stone set ring sizes, whether it be in a retail or workshop environment. Made from powder coated cast iron, this handy tool will stretch the metal by rolling out the shank, therefore enlarging the ring without loosening the prongs or putting stress on the stone settings. Supplied with 17 rollers, which accommodate almost any ring size, they will enlarge rings that are size J and above. Provided neatly contained in a plastic storage box for easy access.
