Here are the extravagant rings given to Super Bowl champions over the years

After the New England Patriots won Super Bowl XLIX in 2015, owner Robert Kraft ordered 150 rings at a cost of $5.5 million.

Each ring cost $36,500, the most ever for a Super Bowl ring made by Jostens.

But to the victor who earns it, the value of the ring exceeds money.

"It isn't just diamond and gold," said Jerry Kramer, a former Green Bay Packer player who won the first Super Bowl in 1966. "It's a collection of memories and moments."

Minneapolis-based jewelry company Jostens is the primary supplier of Super Bowl rings, in addition to manufacturing the majority of high school and college graduation rings in the United States. It has made 31 rings in the Super Bowl's 50-year history.

Jostens provided us with photos of the Super Bowl rings they've supplied. We have added photos of some of the others.
