Treasured Serviette Ring

Pinkhairedlady's Tiny Tuesday challenge is something you treasure.
This is one of five serviette rings given to my grandfather by his workplace when he enlisted in the war. 
I have one, others are spread around the extended family.
I have blipped it before when I thought I had lost it.

Off now to mind the grandkids while their parents go to something at the school (again).
