What Are The Jewelry Rules For Officials?

[Love2ref4Ever]

Over the past few years I have witnessed more and more officials wearing jewelry. Is this accepted by various college conferences and high school boards? Or is it that some officials just don't even care about there apearance. The most noticeable piece of jewelry that I see is the gold chain around the neck. I am married and I don't wear my wedding ring during any games, all though this piece of jewelry I understand is accepted. I would like to know what are the jewelry rules for officials. Or can we as officials do a game with a "MR. T" starter kit on.
