1976 Class ring signed Josten Sterling.  The ring is from McAuley High School in Cincinnati, Ohio.  There is also a monogram on the inside "BLB."  

The ring has a pretty reflective stone reminding me of mother of pearl but it could be art glass.  The crown is 14.5mm and the ring weighs 7.2 grams.  Size 6.  Nice pre owned condition.  

Some photos are enlarged to show detail.  From a smoke free home.  Thanks for looking.
