I found this common sense gem in my archives from the FAA:

Finger Rings
A ring from your mate is great but a ring on the job will make you sob. This tip is short and sweet. Do not wear your ring at work. Can’t get it off? Well then, tape it or glove it.
Let’s be frank, finger rings and aircraft maintenance do not mix well. Don’t think for a moment that your finger can support your weight if you catch it while jumping to the ground from a ladder, maintenance stand or aircraft. It is also a great conductor for electricity and there is plenty of that around an aircraft. While on this topic, don’t ignore any other jewelry on your body. It goes without saying that jewelry looks great when on a date, but on the job it will ultimately lead to an unpleasant fate.
