It is approximately size 8 1/2. It weighs 11.25 grams. It is in very good condition. It does have small nicks but not a lot of wear. If you look very closely there are small chips in the center stone.
I do believe that the center stone is a Ruby, but no guarantee on that. It has the Albany Cougar on one side and the coat of arms on the other side. It is stamped 10k and has engraving DAS inside.
