This is an extremely rare 1990 Winnipeg Blue Bombers "Grey Cup Champions" 10k Gold & Diamond Ring that was presented to CFL player Eric Streater #80. This stunning ring is made of 10k yellow gold and weighs in at a hefty 43.1 grams, with a total of 32 small diamonds in it. The ring was manufactured by Jostens (Stamped: "C" in a circle, JOSTENS 10K). The size of the ring is approximately a 9. This ring is marked "Grey Cup 78", the 60th Anniversary of the Winnipeg Blue Bombers and the tenth Grey Cup Championship that they won. Winnipeg played the Edmonton Eskimos and defeated them with a final score of 50-11.
This is NOT a replica or staff ring. It is a genuine player ring that was never intended to be made available to the public. These Grey Cup rings almost never become available, due to the pride of ownership most players have after earning one. A SUPER investment.
To establish what a great investment this is, here is a current link to TV's "Gold and Silver Pawn" Show, who have 4 Saskatchewan Rough Riders Grey Cup rings for sale from the same era as this one. They are selling theirs for $23,500 each: https://gspawn.com/en-ca/products/2013-saskatchewan-roughriders-cfl-championship-ring

I think they are a little high, so I will consider best offers.
