"I have never seen anything like it," Viasat curling expert Annette Norberg told the Aftonbladet newspaper on Friday after the Chinese team twice failed to let go of the stone in time.
"But it's an easy thing to do when you're a bit nervous. This match had it all," she added.
Swedish curler Victor Kjäll said a bit of help from on high had helped them win 6-4.
"The curling gods were with us today," Kjäll told the newspaper.
As the men's coach Eva Lund flew on to the ice to hug the men after their win, Swedish sports commentators remembered the very near miss four years ago in Vancouver, when the Swiss pried victory out of the Swedes' hands.
The team had to settle for fourth in 2010, which, the team said ahead of Friday's game, had made them all the more determined to take home a piece of metal this year. Niklas Edin, Sebastian Kraupp, Fredrik Lindberg and Viktor Kjäll thus gave Sweden its 14th medal at the Sochi Winter Olympics.
It was the second medal in just one hour on Friday as Sweden's Anna Holm took home a ski cross bronze.
