Up for sale is a used men's size 10 1979 class ring from Bellevue High School in WA State. 

There are what appear to be initials of A B to the left and right of the main stone as shown. 

The inside of the ring is inscribed " Memories of BHS."

The ring was made by Argentus.

The ring appears to be a metal alloy, and I'm unsure of what the stone is made of.
