I hope you never need an MRI. It really doesn't come off?

I guess it could be cut off if I really needed to :) But other than that, no it doesn't come off. You tend to gain weight as you get older, even on your fingers.

Shouldn't you get it adjusted then? I'd be afraid of losing the finger if it gets too tight.

It's not tight enough to be a real concern, just enough that I can't remove it. I think it's more symbolic than anything...the only reason I made it through school was to get the ring and it's a big part of who I am as a person.

Now it is part of my person.

We can usually get new ones for about 15$. I don't think the adjustment costs less. There is also the option of not wearing it, as wearing rings that keeps touching a mouse is annoying sometimes.

I don't think it's ferromagnetic.

Iron is ferromagnetic.

I was thinking of the stainless steel version, but looking that up looks like the answer is "depends". Depends on the definition of "magnetic" (since all materials are to a degree) and the type of stainless steel.

I just noticed that my own "iron" ring (which is stainless steel) doesn't seem to respond to typical magnets you'd find around the office.

Clearly _iron_ is though, considering it's the element with the symbol "Fe" which is short for Ferrum.

Usually (but not always) higher quality stainless steel is not magnetic, while the lower quality is slightly magnetic.

However even slightly magnetic can be a problem in an MRI - and worse, there is no practical way for the MRI tech to tell how the stainless steel will act, so they will err on the side of caution.
