Ring Resizing
Your ring should fit snugly but comfortably. It should slide on easily, but you should have to pull a little to get it off. If your ring is uncomfortably tight, you should look into getting the ring made larger. It should also be sized if it slips off with no resistance at all, which means it is too big.
Typically, rings can be increased or decreased up to two sizes. Beyond that, it can put too much stress on the ring. If you can't have your ring resized until a future date, our jeweler may add a ring guard to make it a little more snug. It's a bar that clips across the bottom of your ring, but it should be used for only a short amount of time. Over time, a ring guard can damage the band.
Unfortunately, there are a few restrictions whereby some rings cannot be resized. To be resized, your ring must be made of metal such as silver, gold, or platinum. Non-metal materials (such as tungsten and titanium) cannot be resized, nor can full eternity bands, or rings with tension settings.
