my husband has slightly sensitive skin, and his work puts the ring and his hands to a bit of a challenge.  i read the reviews that mentioned tungsten could be irritating, so ordered up 1/2 size.  with these conditions, the only time the ring bothers him is if his hands get really warm.

so bottom line:  this ring is really attractive, and you should only hesitate if sensitive skin is an issue.

edit 12/31/12:  sadly this ring has gone on the key chain. It is really attractive but the resulting "ring of fire" made it impossible for him to continue to wear it.  this year for christmas I replaced it with a sterling silver claddagh ring.
