Durston Gem Ring Stretcher

The Durston Gem Ring Stretcher is a professional jewelry bench tool designed to increase the size of stone-set rings without removing the gemstone. It works by stretching the ring shank while keeping pressure away from the setting, helping jewelers enlarge rings safely and efficiently.

Using a set of interchangeable rollers, the tool gently rolls and stretches the bottom of the ring shank, increasing the ring size while minimizing stress on prongs or gemstone settings. This makes it ideal for resizing rings that already contain stones such as diamonds or gemstones.

The stretcher is built from powder-coated cast iron for durability and long service life. Pre-drilled mounting holes allow the unit to be securely attached to a workbench for stability during operation.
