There are several companies that make tension mountings and every one I know of would immediately void the warranty if you do this. Mind you, the process is basically correct but you should be using the ring manufacturer for this job, not a local smith (unless they are the manufacturer of course). They are all quite good about supporting their dealers with this sort of service although sometimes there is a fee. In the case of a new purchase, they will probably simply make the ring in the proper size to start with.Date: 6/14/2005 4:47:43 AM

Can't see why there will be a problem. Not a particulary easy sizing job. If the jeweller selling the ring resises his rings for free, then I'll bet it would eat away at his margin.
To cut the size out you will end up with two pieces. The two halfs need to be rejoined. The metal will have softened with the heat unless a laser welder is used, even so there is still more to do.
Because the metal is now soft it will need to have been sized a bit smaller and hammered up to the desired size. The hammering should harden the metal enough to make the ring secure again.
Then the diamond will have to be re-set.
Hope this helps,
