How is jewellery handled in your leagues?

[mach3]

This is maybe a rules question but also a question how it is dealt with in reality - contests under FED, ASA and NCAA are of interest, but others welcome.
We had a long meeting in the beginning of the season in Germany to discuss jewellery and other issues and decided that we want to have the jewellery removed - not just taped.
Than a colleague recognized in different NCAA games this year (Div I - Div III) that there nobody cared about players wearing jewellery!

How do you handle that issue? If you differentiate, on what basis?

Thanks for your input.
