Deluxe Stone Set Ring Stretcher with 16 Dies and Wooden Box

This ring stretcher will enlarge rings from sizes 3 (14.1 mm diameter) and up. It comes with 16 different dies to fit flat, half-round, and knife-edge shank profiles of widths from 1 mm to 4 mm. This device has 35 mm (0.188”) holes in the base so it can be mounted to a bench or work table with wood screws (not included). It comes in a sturdy wooden box to hold the tool and the dies. Overall measurements of tool: 19 cm x 8.5 cm x 10 cm (7.4" x 3.3" x 3.9”). Easily enlarge any stone-set ring! This device simply works by rolling out the shank to stretch the metal. It will then stretch the ring but avoids loosening any prongs or stone settings. To stretch rings, select and position the correct die. Place your ring on the shaft, and tighten the handle. Carefully rotate the handle 360°, or until your ring is the desired size.
