Re-sizing an Engineer's Iron Ring

2005

I have a stainless steel ring which I have worn for some 28 years. However, it is now rather too tight and a visit to a local jeweller indicates it needs to be up-sized from 7-1/2 to 8-1/2. I was advised that this would require annealing the ring and could be quite difficult or even impossible and could result in the ring being spoiled. Can you advise on how best to proceed.

If you are absolutely sure its stainless steel have it cut and re-welded with the TIG argon welding process. A decent jeweler may then shape it and polish it back. No need to anneal it in my opinion. G. Marrufo-Mexico

Michael,

Contact the BC order of engineers or a school of engineering I'm sure they'll be able to direct you on what to do to replace your ring. Basically all you need is your engineer number (anyways it's the case in Quebec).
