Thanks to this thread, I was reminded to put my ear ring in. A ruby stud in my left ear to be navigationally correct. If I ever get my right ear pierced, I have an emerald stud for that side.
No, really. I do.
As a celebration of our 20th anniversary (it will be here in a few months), my wife and I retired our relatively plain gold bands and replaced them with yellow and white gold bands with 6 diamonds in them.
I wear a gold chain when I go to work as a place to put my ring if need be. My hands shrink and swell quite a bit during the day. So, if my hand has shrunk excessively during the day, I take my ring of my finger and put it on the chain.
Otherwise, I don't wear jewellery. I do have a watch that I wear when I'm teaching motorcycle riding. Beyond that -- nada.
