It's also taking a big chance, as both parties will probably be quite a bit more mature in a few years, and probably regret not getting something with lasting value, such as platinum or a finer grade of gold. ... Good ones feel like some metal of the gods due to the massive weight for such a small piece. Not enough to get make your finger tired, but enough to surprise people who have only held gold.

Consider that iridium is much rarer, more valuable, and heavier than gold or platinum. It is also much harder and more resistant to scratches.

I don't know how easy it is to remove. Depending on how hard/brittle iridium is, it may be more like tungsten carbide (WC). A ring made of "uncuttable" WC can be easily and safely removed by breaking it using vise-grip pliers (like this).

Some quick research shows that iridium has a similar Young's Modulus to WC (~530 GPa and ~700 GPa respectively) and about double the tensile strength of WC (~600 MPa vs. ~350 MPa). So it might be removable in a similar fashion. Of course you should check by experiment if possible before any emergency comes up!

(I got the above data from here, here, and here.)
