Ring Stretcher-Rathburn

Rathburn ring stretchers are a simple and easy way to enlarge basic plain wedding rings.  They are not for use with stone set rings.  As with any ring stretching device, care must be taken by the user to inspect for previous solder welds in the band that might break if you attempt to stretch a band with this tool. After ring is placed on stretcher and tapered part is inserted, gentle tapping with mandrel causes ring to expand. This Rathburn ring stretcher will stretch rings starting with USA size 8-1/2  to  size 15.  Ring size smaller than 8-1/2 will not fit on the mandrel.
