will 9ct gold stretch as much as sterling when I hammer it?
I have made and sold a lot of textured silver rings I have named 'well hammered' (see pic). I have to start them 5 sizes smaller as they stretch so much when I hammer them on a tapered ring mandrel. My daughter now wants me to make her wedding ring with my well hammered technique, which just means hammering the entire surface of the ring with a ball pein hammer.
Because she wants it made in gold I need to know what size to start it off at, to arrive at her required UK size P.
Can anyone advise me on this?
