I have a small tungsten band with a S&C laser-engraved on 4 sides of it.

It looks similar to the link below however the color is a bit more faded and the S&Cs are all facing the same way.

Either way it was a casual reminder to myself that I am a Mason and should govern myself accordingly and it was subtle so it wasn't saying "HEY GUYS I'M A MASON!"
