The short answer is yes, you can resize titanium rings. However, this isn't the case for all of them. Titanium is a popular alternative metal due to its affordability, durability, and looks. Titanium is more scratch-resistant than white gold. It is a hard and durable metal, but still soft enough to be sized up and down. Lastly, titanium has a beautiful natural color similar to stainless steel. Titanium wedding bands look terrific when properly polished and can hold a shine incredibly well. It is a bit difficult to work with and machine, but the proper jeweler will be able to resize a titanium ring. There are a few different factors that contribute to whether or not you can increase or decrease the size of a titanium band.
The first is the grade of titanium. Grade 5 commercially pure titanium is the most common material that rings are made from. This metal is actually quite stretchable and can be increased by up to two sizes in some cases.
Similarly, you can compress a ring with an inlay as long as you only go down about one size. Precious metal inlays or those with gemstones may change your ability to resize, so you'll need to talk to an expert about how to alter it. The process of sizing down a titanium ring is a lot trickier than sizing up. Most jewelers will be able to size up titanium wedding bands, but some will not be able to size them down.
While it is best to find your size before ordering, it isn't all gloom and doom if you gain or lose weight later. Take care to select the right size initially, but don't stress about what will happen if your fingers alter in size.
