Titanium Ring Resizing

· Grade of Titanium

· Is it diamond set?

· Does it have a precious metal inlay?

· Does it need to go up or down in size.

Whilst it isn’t normally within the capabilities of a normal jeweller to do a quick resize, there is often various options that the manufacturer can take.

Grade 2 commercially pure Titanium is fairly ductile and will stretch and compress quite readily. If it has a precious metal inlay set into the outside it is probably better to take a skim out of the bore to make it bigger – stretching will normally cause the inlay to split. The amount of increase could be up to about two sizes. Compressing a ring with an inlay is usually OK for about one size. Compressing plain rings depends on the outside pattern. If it is patterned then the amount of force required to compress it will undoubtedly cause too much damage to repair the outer surface economically and so should be avoided. Plain domed or flat rings don’t present much of a problem.

Higher tensile grades of titanium, such as aircraft grade Ti/6Al/4V (or grade 5 as it is also known) will not stretch or compress. The only option with these is to increase the ring size slightly by remachining the bore larger.
