not directly related, but diamond could be used as a watch jewel. In mechanical watches artificial sapphires are used. Metal on metal is too clingy. So the axel part of a rotating system is a jewel onto a metal stator. If you buy a 14 jewel watch there are 14 of these joints in it. Not to do with bling.
