Is this monitoring jewelry? Initially I was with most of you as this initially seems to be inappropriate equipment for basketball. However.... Where does it fit in with Rule 3-5?

I think that the casebook(3.5SitA)covers this one pretty well:
1)"Equipment which could cut or cause an opponent to have an abrasion is always illegal and,therefore,is illegal".
2)The prohibition of the use of hard substance material does NOT apply to the upper arm,shoulder,thigh or LOWER LEG if the hard material is appropriately padded so that IN THE JUDGEMENT OF THE REFEREE it is not hazardous to others".

The referee's judgement is always the determining factor.IMO,if they cover and pad it,I can't see why you wouldn't let him play.
