Odd wedding ring materials?
i was thinking about getting a wedding ring in the future and i am not the kind of person who likes to be traditional. My girlfriend is worth everything to me so a ring that would be worth almost as much as her would be a diamond ring made out of osmium, iridium, osmiridium, or platinum. i know that these are all in the platinum family (group) but would any of these make good materials for a ring? i would like an unusual material that possibly has some cool properties (like osmium has a cool blue tint).
P.S. i know that osmium when oxidized has a smell and is toxic (and will cause the skin to turn black) i also know that platinum is a "traditional" wedding ring material and therefore can be made into a ring but the others i am unsure about.
